    New Ternary Intermetallics Based on Magnesium for Hydrogen Storage: The Fishing Approach

    Magnesium allows obtaining a good hydrogen storage capacity in terms of weight percentage but its use is limited by high stability of the hydride and slow kinetics. The kinetics can be improved by (i) mechanic...

    On the CVD of MoSi2: an experimental study from the MoCl4–SiCl4–H2–Ar precursor with a view to the preparation of C/MoSi2/SiC and SiC/MoSi2/SiC microcomposites

    The chemical vapour deposition of MoSi2 on plane substrates (graphite or sintered-SiC) and ceramic fibres has been studied from MoCl4–SiCl4–H2–Ar gas mixtures at 900<T<1400°C and 2<P<40 kPa, according to an ex...

    Estimation of residual stresses in SiC/Ti-15-3 composites and their relaxation during a fatigue test

    Residual stresses induced by cooling down from the elaboration process in SiC/Ti-15-3 composite were calculated by the finite element model using MARC and MENTAT software. An analytical model (derived from tho...
