Abstract

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 to the large compressive deformability with plastic strains up to 15%.
