Abstract

A large tensile plastic deformation was achieved in ZrCu-based metallic glass composites with a metastable B2 phase. It was found that the B2 phase can effectively promote the density of the stress concentration sites and enhance the formation and interaction of multiple shear bands, which significantly stabilize the tensile plastic deformation of metallic glass composites. Based on the concept of the normalized strain-hardening rate, the critical volume fraction for the stable tensile plastic deformation of metallic glass composites was determined.
