4 Elemental grain boundary segregation and geometry during spark plasma sintering of multi-component carbides

Multi-component carbides are promising materials for ultra-high temperature applications, offering greater tunability of properties and design flexibility. However, they still suffer from processing challenges that must be addressed before full advantage can be taken during use in advanced technologies. In this study, we describe the spark plasma sintering and grain boundary characterization of (Mo-Nb-Ta-V-W)C (MNTVW-C) multi-component carbides. Specifically, we describe variations in grain boundary chemistry in MNTVW-C, sintered from either the single-phase rock-salt carbide powder, or from powders that include the rock-salt carbide phase, Mo2C and W2C. Grain boundaries in the sintered ceramic fabricated from the pure carbide powder possess greater levels of tungsten segregation. Additionally, the grain boundary geometry varies significantly between samples. The concentration (measured in percent length) of lower energy special grain boundaries is increased measurably in the ceramic prepared from multi-phase powder. These microstructural variations may have consequences in the bulk MNTVW-C behavior connected to fracture strength, creep resistance, oxidation behavior, and thermal or electrical transport. Grain boundaries can act as fast diffusion pathways and preferred sites for chemical reactions, making their local composition especially influential in high-temperature and extreme environments. These effects will be considered in detail during this talk.

5 High-Intensity Electric Nano Pulsing

A novel field-assisted materials processing technique based on the electro-nano-pulsing (ENP) method has been developed, along with a device capable of applying electric pulses with ultra-high intensity (~10¹¹ A/m²) and ultra-short duration (<1 μs).
This technology activates non-equilibrium structural evolution at nanometer spatial scales and nanosecond temporal scales, primarily affecting grain boundaries in polycrystalline materials. Owing to the large difference in electrical resistivity between the grain interiors and grain boundaries, highly localized Joule heating can be achieved.
Additional effects include localized modification of the material structure at the micro- and nanoscale without significant changes in grain size. Ni–Cr wires processed by ENP exhibit unique structures and properties.
Beyond bulk materials processing, the ENP technology has been extended to electrically driven, non-equilibrium densification of powder materials. Ultra-rapid neck formation and densification occurring within milliseconds have been demonstrated, for example, in pressure-assisted ENP sintering of 316L stainless steel. Experimental observations of electrically driven mass transport and interfacial phenomena at the particle scale provide new insights into the fundamental mechanisms of electric field-assisted sintering.

6 Experimental and numerical investigation of thermo-electric phenomena in SPS sintering

SPS is a powder consolidation process that employs electric current to generate heat (Joule effect) while simultaneously applying pressure to achieve densification. In conductive powders, as current flows through the network of particles, it can concentrate at interparticle contacts/necks due to high resistance. This may result in high current densities and local temperature increase (overheating). Such thermo-electric effects can influence microstructure and hence properties.
In this work, thermo-electric phenomena during SPS are investigated through a combined experimental and numerical study. NiAl powder is consolidated at different temperatures. The resulting microstructures are characterised using XRD, SEM and EBSD, with particular focus on particle contact regions that are most susceptible to local overheating. To complement the experiments, thermo-electric finite element simulations are performed using representative three-particle geometries with different neck sizes.
The combined experimental and numerical results indicate that the resulting overheating in NiAl is limited and insufficient to induce partial melting or microstructural changes under the investigated conditions. These findings contribute to a clearer understanding of thermo-electric phenomena in SPS and suggests that a numerical model of SPS can be simplified.

7 Digital twin for thermal management in spark plasma sintering

The transition of SPS from research to industry faces several challenges. Upsizing leads to temperature inhomogeneity within the sintered part. Another challenge is the enormous power required for heating. The proposed digital twin addresses these issues by optimizing the SPS tooling. The digital twin was validated by sintering 3YSZ samples at 1350 °C and then heating them to 800 °C. The die used had an internal diameter of 50 mm. In the first case (1350 °C), the K-type thermocouple measured the temperature at the external surface of the graphite felt insulation. In the second case (800 °C), the thermocouple measured the die wall temperature. Comparison of the measured temperatures with the digital twin predictions shows good agreement. The digital twin application is highly efficient. Optimizing the SPS tooling reduced the temperature difference between the edge and the center of a 50 mm 3YSZ disc from 88 °C to only 3 °C during the dwell at 1350 °C. At the same time, the power decreased 2.5-fold, and the total sintering energy was half that with non-optimized tooling. The effect of optimization increases with sample diameter. For example, optimizing the tooling for sintering 100 mm 3YSZ discs reduced the temperature difference between the edge and the center during the 1350 °C dwell from 302 °C to 12 °C. The accompanying power reduction was threefold. The total sintering energy was half that required with the non-optimized tooling.

8 Contamination, Phase Composition and Microstructure of SPS Zr–50%Ti Produced from Powders Obtained by Mechanical Synthesis and Plasma-Based Ultrasonic Atomization

Commercial Zr–xTi powders are unavailable because zirconium alloys are difficult to synthesize due to high reactivity and ignition risk. High-zirconium Zr–xTi biomaterials have received limited attention, and the optimal Zr/Ti ratio for medical use is still unclear. Zirconium and titanium show infinite solid-state solubility; however, most research powders are produced by mechanical alloying (MA), which can markedly affect the phase constitution and microstructure of SPS-sintered parts. Here, Zr–50%Ti powder was prepared by two routes—MA and ultrasonic plasma atomization—using the same elemental Ti (APS, 98.5%; 45 µm) and Zr (APS, 99.9%; 45 µm) feedstock. Blends were mixed in a planetary mill (100 rpm, 36 h) with zirconia bowls and balls. Powder purity, morphology and particle size were evaluated, including laser particle-size analysis. MA produced finer particles (average 19.63 µm), whereas the atomized powder showed a bimodal distribution with a larger mean size (34.9 µm). Both powders were SPS-sintered at 1000–1100 °C. Phase composition was assessed by X-ray diffraction and microstructure by SEM; oxygen, nitrogen and hydrogen contamination was quantified in the sintered materials. Overall, MA-derived specimens exhibited more complex phase composition and microstructural features than those obtained from atomized powders. These results indicate that powder-production route is a key driver of structural heterogeneity and impurity uptake in Zr–Ti alloys processed by SPS.

9 Visualizing heterogeneous microstructures and defects in ceramics using synchrotron X‑ray multiscale tomography

Synchrotron X‑ray multiscale tomography, combining micro- and nano-tomography, provides high-resolution 3D imaging of heterogeneous microstructures and defects in ceramics. This method reveals how powder heterogeneity, hierarchical structures, and complexity govern defect formation, reliability, and mechanical performance.
In multilayered ceramics, defects arise from raw powders or during tape casting, drying, thermo-compression, binder burnout, and sintering. Tape-cast alumina laminates show strength-limiting defects at layer interfaces and around large powder inclusions. Even uniform slurries exhibit heterogeneous particle packing, forming complex interconnected pores, while self-assembly of polyhedral alumina crystals can produce flake-like sheets for controlled 2D microstructures.
In high-purity submicron α-alumina, agglomerates and aggregates evolve into complex pores during sintering. Circumferential cracks form under matrix constraint, and fractography confirms these pores as fracture origins. Mechanical analysis using elliptical crack and pore-crack models explains the observed strength.
These studies demonstrate how synchrotron X‑ray multiscale tomography links powder heterogeneity, processing, and strength-limiting defects, guiding the design of high-reliability ceramics.

10 Relationship among Grain Growth Behavior, Electrical Properties, and Crystal Structure in Dielectric Ceramics

Microstructure plays a key role in governing the functional properties of electronic ceramics. In this study, the relationship among grain growth behavior, crystal structure, and electrical properties is investigated based on the theory of two-dimensional nucleation–controlled grain growth. Perovskite systems, including barium titanate, barium calcium titanate, and sodium potassium niobate, are employed as model materials to examine the effects of various additives on grain growth and microstructural evolution. The results show that additive-induced modifications in interfacial and crystal structures significantly alter grain growth kinetics, resulting in distinct grain size distributions and growth behaviors. These variations are closely associated with phase stability, lattice distortion, and symmetry, depending on composition and additive chemistry. The underlying mechanisms are discussed in terms of interfacial energy and two-dimensional nucleation processes at grain boundaries. Dielectric properties, particularly relative permittivity and dielectric loss coefficient, are evaluated as functions of frequency and temperature. Strong correlations are observed between grain growth behavior, crystal structure, and dielectric response. The results demonstrate that controlled grain growth and structural tuning through additive engineering provide an effective approach to tailoring the frequency- and temperature-dependent dielectric performance of perovskite electronic ceramics.

11 Preparations and characterizations of low-cost porous ceramic membranes

Porous ceramics are widely studied for their superior thermal and chemical stability compared to porous metals and polymers. Reticulated porous ceramics, in particular, offer low density and high permeability, making them promising for air filtration, although their relatively low compressive strength still limits broader application. Porous ceramic membranes have also gained importance in water treatment due to their robust thermal and chemical resistance. To reduce manufacturing costs, increasing attention has been given to low-cost raw materials such as diatomite, kaolin, pyrophyllite, and silicon carbide.

This study explores strategies to enhance the compressive strength of low-cost reticulated porous ceramics by optimizing process parameters including solid loading, particle size, and additives in ceramic slurries. In addition, we investigate the fabrication of extruded porous ceramic membranes with controlled pore characteristics—average and maximum pore size, pore distribution, and structure—while maintaining desirable mechanical strength and permeability. The analysis includes pore properties (density, size, and morphology), sintering behavior (linear shrinkage), and mechanical performance (compressive and flexural strength). Characterization techniques such as scanning electron microscopy, mercury porosimetry, capillary flow porosimetry, and dead-end microfiltration with particle counting are employed to systematically evaluate air and water permeability.

12 Low-temperature sintering of titanium-based perovskite-type oxide semiconductors using alkali metal vapor

Introduction
Titanium-based perovskite-type oxide ceramics for variable resistors [1] are conventionally produced by sintering green compacts in reducing atmospheres at ~1400 °C. We report the use of Na or K metal vapor to obtain conductive ceramics of CaTiO₃, SrTiO₃, and BaTiO₃ below 1000 °C.

Experimental
Powder compacts of CaTiO₃, SrTiO₃, and BaTiO₃ were placed into a boron nitride crucible and enclosed in a stainless-steel (SUS) container with Na or K metal in an Ar atmosphere. The containers were heated at 600–1000 °C for 1–10 h. Relative densities (RDs) and microstructures of the samples were evaluated by the Archimedes’ method and scanning electron microscopy.

Results and Discussion
BaTiO₃ densified at the lowest temperature (~750 °C); maximum RDs (>96%) were achieved at 800–1000 °C for 2 h and the ceramics were conductive (~300 Ω cm) due to the reductivity of Na. Conductive ceramics of other perovskites were also obtained at 900 °C for 10 h. Cuboid grains in the ceramics suggests that a dissolution–precipitation process mediated by condensed Na vapor facilitates low-temperature densification. Furthermore, conductive BaTiO₃ ceramics were obtained in the same temperature range with K vapor.

13 Intertwined Processes of Coarsening, Densification, and Grain Growth during Sintering of Nanosized Particles

Sintering is one of the main and few approaches for building bulk ultrafine-grain materials from the bottom up. One of the main challenges in sintering nanosized powders is controlling grain growth while achieving full densification. Considerable literature is now available for identifying unique mechanisms that could provide clues to achieving densification with minimal grain growth. It is critical to understand the detailed mechanistic steps to design processes that can lead to bulk materials with maximum density and minimum grain size. Using experimental data of sintering nanosized tungsten carbide and tungsten powders, this presentation examines the intertwined processes of neck growth, coarsening, densification, and grain growth. When the density of the compact of nanosized particles is very low, coarsening of particles is responsible for most of the observed initial grain growth. Coarsening also contributes to densification. Because initial coarsening depends on surface diffusion, surface diffusion indirectly also contributes to densification.

Sintering for additive manufacturing

14 Fast laser processing and densification of silicon carbide ceramic materials

SiC-based Ceramic composites are promising for usages as various large-scale and complex-shaped components. However, the intrinsic brittle nature of SiC ceramics inhibited their wide application. Incorporation of chopped carbon fiber as a reinforcing phase could enhance its reliability. During recent years, efforts have been devoted to fast forming techniques to reduce excess carbon reduction. Additive manufacturing of SiC-based ceramics by adopting various techniques, including digital light processing, direct ink writing, selective laser sintering, and et al were emerged.
In previous study, our group conducted investigation on direct ink writing of C/SiC ceramic composites. The critical point was the preparation of homogenous C/SiC green bodies. In recent study, we combined selective sintering and liquid silicon infiltration for a higher-efficiency and higher-performance-component fabrication. We prepared complex-structured composites therefrom. The relationship between microstructure tailoring and mechanical performance was investigated.

15 Dimensional and Geometrical Changes During Sintering of Binder Jetting Components

In this study, the sintering behavior of stainless steel 316L components produced by binder jetting process is detailed. It explores the effects of initial particle/pores distribution, gravity, and friction on sintering, leading to anisotropic shrinkage and shape distortions. Dilatometry tests were conducted to experimentally investigate the anisotropy behavior and microstructural evolution at different sintering temperatures.
The influence of the gravity and friction forces during sintering are experimentally investigated through the analysis of the distortions developed in sintered parts with overhangs and tee-pipe connectors. Moreover, in this work, the novel sintering simulation framework for gravity-affected sintering of stainless-steel including the Rios-Olevsky-Hryha sintering model and the constitutive law which includes material constants to account for the powder packing effects and the delta-ferrite transformation occurring at high temperatures is presented.

16 Thermal Anisotropy in Chopped Cf Reinforced SiC Composites by Laser Printing and Polymer Infiltration-Pyrolysis Techniques

Directional thermal transport materials enable anisotropic heat flow, thereby enhancing the efficiency of thermal management systems. These materials have found broad applications in aerospace, electronics, and automotive industries. Silicon carbide (SiC) based composites, with their exceptional properties including high modulus, thermal stability, and superior thermal conductivity, serve as an ideal structural material. Strategic manipulation over microstructure and composition enables directional thermal management, expanding applicability in thermal management and achieving structural-functional integration. By combining selective laser printing with precursor impregnation and pyrolysis (PIP), this work presents an innovative approach to fabricating thermally anisotropic Cf/SiC composites that integrate both structural and functional properties. The optimized composite (20% (in volume) chopped Cf) exhibited high fiber alignment (fp = 0.7677) and pronounced thermal anisotropy, with thermal conductivities of 70.14 W/(m·K) perpendicular and 38.87 W/(m·K) parallel to the printing plane (anisotropy ratio: 1.8). This directional heat transport, enabled by fiber orientation and phonon scattering control, is critical for advanced thermal management. The composite also maintained good mechanical strength, exhibiting a flexural strength of (150.4 ± 9.8) MPa parallel to the printing plane, finalizing in a structural and functional integration.

17 Direct selective laser sintering and properties of SiC ceramics doped with Al2O3-Y2O3

Direct Selective Laser Sintering (DSLS) of SiC ceramics offers a rapid and efficient approach for fabricating complex shaped porous SiC structures, positioning it as a promising additive manufacturing technique for such materials. However, the inherent difficulty of maintaining a stable liquid phase in SiC introduces challenges during laser based solid state sintering, such as slow diffusion kinetics and insufficient interparticle bonding, leading to poor mechanical integrity in the sintered ceramics. This study explores the influence of Al2O3-Y2O3 liquid phase sintering additives on the porosity, microstructure, and physical properties of SiC ceramics sintered under varying energy densities. The results demonstrate that by modulating the energy density during DSLS from 5.5 J/mm2 to 13.9 J/mm2, porous SiC ceramics can be obtained with porosities ranging from 45.57% to 56.91%. As energy density increases within this range, the compressive strength increases from 25.00 MPa to 181.80 MPa, thermal conductivity from 6.12 W·m-1·K-1 to 15.66 W·m-1·K-1, electrical resistivity from 4.17 Ω·cm to 34.58 Ω·cm, and specific compressive strength from 17 MPa·cm3·g-1 to 97 MPa·cm3·g-1. This work elucidates the microstructural evolution and correlated variations in the physical properties of DSLS fabricated SiC ceramics facilitated by Al2O3-Y2O3 liquid phase sintering aids.

18 Development of Sintering Methods for Near Net Shaping of Copper by Selective Powder Deposition

In the current day industry laser based Additive Manufacturing (AM) of metals is a well-established production technique. Its main limitation, linked to inherent the rapid melting and solidification, is the narrow range of compatible materials. In comparison, sintering based AM offer a potentially much larger library to select from, including many of the traditional Powder Metallurgical materials. Most commercially available solutions are based on binder jetting, material extrusion and stereolithography. These, however, all share the same disadvantage in the need to remove binder prior to consolidation by sintering. This can limit the applicable range of obtainable geometries, instilling a strong preference for thin-walled parts.
Previously the use of Selective Powder Deposition (SPD) combined with sintering was proposed as an alternative AM method avoiding the need for debinding. In SPD multiple powders can be stacked in a layerwise manner to form a 3D powder construct. If one of these powders is an inert non-sintering material, then in theory parts, mono- or multi-material, can be obtained via heat treatment of this powder construct. In this, the sintering is the crucial step determining both material properties and geometrical accuracy.
In the current work we present an extensive study into the densification of copper parts obtained via the SPD route. The influence of several sintering methods, atmospheres and thermal cycles are examined in relation to material properties.

19 Sintering Hazards - A Non-Steady-State Approach to Kinetics

In situ TEM based sintering experiments indicate that sintering kinetics are inherently non-steady-state due to the need to nucleate point defect sinks. In materials science, kinetic laws are typically derived from differential equations describing the relationship between instantaneous rate and driving force. These formulations are not adequate for problems that are inherently non-steady-state, exhibit hysteresis, and stochasticity. To address this problem, we invoke lifetime and hazard analysis, which is better suited for such problems. We demonstrate that this analysis enables the formulation of a closed form kinetic equation that converges (i) on Coble's equation when the hazard is large, (ii) on a nucleation rate limited model when the hazard is low, and (iii) the sink-controlled regime first derived by Ashby et al for intermediate hazards. This provides a basis for predicting the general sintering response across all rate controlling mechanisms.

Photonic sintering

20 Laser Sintering of alumina

A direct laser sintering process that uses a high-intensity continuous wave (CW) laser as the heat source has been developed and 1 mm thick alumina was successfully sintered by laser irradiation for 1 minute. In this process, a YAG laser (or a fiber laser with a similar wavelength) with weak absorption was used instead of a conventional CO₂ laser, which is strongly absorbed by alumina. We found that preheating the alumina improved absorption. Laser sintering of high-purity alumina produced porous bodies with 60% porosity and a bending strength of 200 MPa due to selective powder surface heating. Sintered bodies composed of large crystals (1 mm in size) can be obtained from a mixture of coarse and fine alumina particles by selectively melting the fine particles under laser irradiation. Furthermore, we developed a novel laser sintering aid that preheats the alumina body under laser irradiation, functioning like conventional sintering aids. This aid was confirmed to enable high-density sintering in a short amount of time by promoting liquid-phase sintering under laser irradiation.

21 Evaluation of Laser-Assisted Sintering as an Advanced Processing Technique in Traditional Ceramic Industry

Traditional ceramic products are widely used in the construction sector due to their high mechanical strength and chemical resistance. Owing to their ability to maintain performance throughout the lifetime of a building, these products offer significant sustainability advantages compared to alternative materials. However, the ceramic industry is an energy-intensive sector, mainly because of the high sintering temperatures required during production. In the ceramic industry, sintering energy supplied by natural gas–fired kilns, which leads to substantial carbon dioxide emissions. In addition, the thermal efficiency of continuously operated industrial kilns is relatively low due to substantial heat losses, which increases both production costs and emission levels. This situation constitutes a major constraint with respect to the sector’s objectives for reducing its carbon footprint. Within the scope of this study, the feasibility of laser-based energy sources in conventional ceramic manufacturing processes was investigated for both vitrified sanitary ware and ceramic tile products. The physical properties of the laser-assisted sintered samples were examined in terms of physical properties and microstructure. The integration of laser-based applications into ceramic manufacturing processes offers an alternative processing route that enables improved energy efficiency while aligning with strategies aimed at reducing sector-wide carbon dioxide emissions.

22 Microstructure and mechanical properties of photonic sintered silver doped yttria stabilized zirconia

Photonic sintering is a promising alternative to conventional furnace sintering, offering extremely high heating rates and significantly reduced processing times. The process relies on high-intensity light irradiation to directly couple energy into the surface of ceramic powder compacts, enabling rapid heating and densification.
In this work, photonic sintering of silver-containing 3 mol% yttria-stabilized zirconia (3Y-TZP) was investigated using short-wavelength laser irradiation. The small silver addition was used to improve optical absorption and enable efficient coupling of the laser energy into the ceramic powder compact. Cylindrical green bodies were sintered at peak temperatures between 1225 °C and 1550 °C with dwell times as short as 30 s and compared to conventionally sintered reference samples.
Rapid densification behavior, microstructural evolution, and mechanical performance were systematically investigated as a function of sintering temperature and dwell time. In addition, the temporal evolution of laser power during sintering was analyzed to gain insight into the dynamic laser–material interaction. The role of silver redistribution and evaporation, as well as transient thermal gradients across the sample thickness and their influence on local microstructural development, was also investigated.

23 Photonic Sintering of Fe-doped SrTiO3: Impact on sintering, microstructure evolution and functional grain boundary properties

Conventional sintering methods are costly, energy intensive and rather inefficient processes. Photonic sintering (illuminating ceramic samples with high intensity light) has been proven to be an effective method for sintering ceramics. The process readily works for many material systems, yet the fundamental understanding on how the process can be controlled, or how it impacts the ceramics properties is lacking.
The current study investigates the impact of different ultra-high heating rates on the sintering rates, grain growth rates and grain boundary properties of doped and undoped SrTiO3 material systems.
Sintering rates are determined by video documentation data and grain growth rates are determined by SEM imaging. The grain boundary properties are investigated using electrochemical impedance spectroscopy. All data of samples thermally treated by photonic sintering method will be compared to samples from conventional sintering methods.
