Diamond reinforced Al-based bulk metallic glassy composites with improved plasticity fabricated by cold hydro-mechanical pressing

Diamond reinforced Al-based metallic glassy composites with high strength and improved plasticity were fabricated using a novel cold hydro-mechanical pressing (CHMP) of Al85Ni10Ce5 glassy/nanocrystalline powders. The glassy microstructure was retained after consolidation at room temperature and the strong bonding caused by severe deformation between the particles was responsible for excellent mechanical property of the bulk composites. Furthermore, an Al-based glassy alloy composite gear part was obtained due to the advantage of near-net-shape forming for CHMP. The experimental results suggest that Al-based metallic glasses/composites prepared by CHMP have engineering application potentials.
