Abstract

A composite microstructure consisted of μm-scale Ta-rich solid solution particles distributed in the bulk metallic glass matrix was successfully obtained by injection casting of the (Cu60Zr30Ti 10)95Ta5 alloy into a copper mold. The (Cu 60Zr30Ti10)95Ta5 bulk metallic glass matrix composite shows compressive strength of 2320 MPa and, in particular, a significantly improved plastic strain to failure of about 14.5%. The remarkable ductility improvement in the (Cu60Zr 30Ti10)95Ta5 composite could be explained by the presence of the highly ductile Ta-rich particles.
