【 摘 要 】

Two stoichiometric Cu-Zr phases, namely B2 CuZr and CuZr2, are capable of undergoing significant plastic deformation in compression combined with work-hardening. While the former shows transformation-induced plasticity, there is no phase change during deformation of CuZr2. Addition of Al or Ti has a strong influence on the characteristics of the deformation behaviour of B2 CuZr. These insights could prove useful for understanding the mechanical properties of related bulk metallic glasses (BMGs) and could help synthesize new BMG matrix composites.
