Abstract

A novel Mg-14Li-3Al (LA143) matrix composite reinforced with YAl ₂ intermetallics particles was developed by stir-casting. The microstructure and interface characteristics of the YAl_2p/LA143 composite were investigated. The results show that, YAl₂ particles distribute uniformly in the composite, and a good interfacial bonding is obtained with no reaction products at particle/matrix interfaces. YAl _2p/LA143 composite exhibits excellent mechanical properties. The tensile strength and yield strength are significantly improved by the addition of YAl₂ particles, while a good ductility property is kept. During tensile deformation, YAl₂ particles may prevent the propagation of crack in microscale. The YAl₂ particles can be compatible with the deformation of the matrix due to their deformation, exhibiting a "soft" restriction to the matrix. Therefore, the strength and toughness of the YAl_2p/LA143 composite can be improved by the above effects.
