摘要：

Plastic deformation of Cu Zr (Al,Ti) bulk metallic glass (BMG) composites induces a martensitic phase transformation from the B2 to the B19' CuZr phase. Addition of Ti to binary Cu Zr increases the temperature above which the B2 CuZr phase becomes stable. This affects the phase formation upon quenching in Cu Zr Ti BMG composites. The deformation-induced martensitic transformation is believed to cause the strong work hardening and to contribute 10 the large compressive defortmability with plastic strains up to 15%.
