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.
