| Abstract: | The influences on properties of Mg-Li-Al based composites by adding YAl2 particulates were studied.The results show that the addition of YAl2 particulates improves the mechanical properties of the composites effectively.Meanwhile,the tensile strength,the yield strength and the deformation resistance at high temperature of composite are improved significantly while good ductility property is kept. |
