    2. Invited speaker (by invitation only)

    Understanding the true sintering mechanism of metal powders in the initial-stage remains challenging because most experimental and numerical studies rely on two-dimensional observations, which cannot fully capture the three-dimensional (3D) arrangement and topological evolution of particles. Recent in-situ X-ray computed tomography (CT) studies have enabled direct 3D observation of sintering...

  2. 186. Sintering of oxides: the significant impact of carbon on densification kinetics
    Etienne Martin (Université de Toulouse, Toulouse INP, CNRS, CIRIMAT, Toulouse, France)

    In situ measurements and analysis of sintering
    3. Oral presentation

    Advanced manufacturing processes for ceramics, such as non-conventional sintering techniques and additive manufacturing, frequently introduce carbonaceous contamination into oxide-based samples. In this study, we investigate how carbon affects the densification kinetics of Al₂O₃ and Y₂O₃-stabilized ZrO₂ ceramics, focusing on both the underlying mechanisms and the quantitative impact. The...

  3. 25. Grain boundary engineering of low yttrium doped barium cerate through lithium sintering aid infiltration

    In situ measurements and analysis of sintering
    3. Oral presentation

    The development of efficient proton-conducting electrolytes is limited, in part, by strong grain-boundary (GB) blocking effects in acceptor-doped perovskites such as BaCe1-xYxO3-δ (BCY). In this work, we implement a grain-boundary engineering strategy to introduce controlled amounts of lithium nitrate at the BCY GB. The infiltration efficiency was evaluated using three different techniques:...

  4. 173. Towards a better comprehension of high-pressure sintering mechanisms through in situ approach.

    In situ measurements and analysis of sintering
    3. Oral presentation

    Powder sintering is based on diffusion mechanisms, densifying or not, activated by energy input. To enhance its energy efficiency, reduction of sintering temperature is a major challenge. Some advanced techniques (Hot Pressing, high pressure, Cold Sintering Process, Spark Plasma Sintering, …) enable reaching high density while reducing sintering temperature compared to conventional processes...

  5. 104. Study of the interaction between UO2 and U3O8 during the sintering of nuclear fuel pellets
    Antoine Rousselot
    03/09/2026, 10:50
    In situ measurements and analysis of sintering
    3. Oral presentation

    Nuclear fuel pellets are manufactured by sintering UO2 with addition of U3O8 to control the microstructure and porosity. The aim of this study is to determine the impact of morphology and grain size of the U3O8 powder on the sintering. To assess the presence of chemical interactions between the two uranium oxides, the early stages of...

  6. 109. In-Situ Informed Data-Driven Modelling of Fast-Firing Liquid-Phase Sintering of Aluminosilicates

    In situ measurements and analysis of sintering
    3. Oral presentation

    The evolution of microstructure, reaction kinetics, and thermal and mass transport is tightly coupled when designing industrial sintering programs. For aluminosilicate systems, used for white-tiles and structural ceramics, densification is highly sensitive to local heterogeneities and thermal phenomena near the onset of liquid-phase formation. Under fast-firing conditions, high heating rates...

  7. 190. Enhancing Diamond Retention in Bronze Bonded Grinding Tools
    Ertuğrul İşlek (Eskisehir Technical University)
    03/09/2026, 11:30
    In situ measurements and analysis of sintering
    3. Oral presentation

    Diamond grit retention is a critical determinant of the operational performance of bronze-bonded grinding tools, primarily governed by the mechanical interlocking induced by thermal expansion difference between diamond and bronze. This study investigates pressure-assisted densification kinetics of diamond reinforced (10, 46 and 107 µm) bronze composites to enhance interfacial bonding via Spark...
