摘要: A modified Zr-based bulk metallic glass matrix composite Zr47.67Cu40Ti3.66Ni2.66Be6 has been produced by increasing the contents of elements Zr and Cu with higher Poisson ratio reducing Ti, Ni, Be lower based on famous former Vitreloy 1. compressive yielding strength 1804 MPa, fracture 1938 MPa 3.5% plastic strain was obtained for composite. Also, work-hardening behavior observed during experiment which ascribed to interaction in situ precipitated CuZr phase shear bands.
