摘要: Abstract We report the development of a novel light-weight Al (520) alloy-based composite reinforced with particles Cu-based (Cu 54 Zr 36 Ti 10 ) metallic glass by mechanical milling followed induction heated sintering. The consolidation is performed at temperature in super-cooled liquid region just above its glass-transition ( T g ). Metallic glasses are promising alternative reinforcement material for metal-matrix composites capable producing significant strengthening along «friendly» sintering behavior. procedures were properly established to allow reduction size and their uniform distribution matrix. Microstructural observation did not reveal any porosity. interface between glassy matrix remained free such defects. fully dense consolidated showed drastic gain specific yield strength under compression relative alloy appreciable plasticity fracture.
