Deformation-induced microstructural heterogeneity and rejuvenation in a Zr-based bulk metallic glass
Source abstract
Abstract
Abstract Phase separation has been observed in the glassy matrix of (Zr62.5Cu22.5Fe5Al10)94Nb6 bulk metallic glass (BMG) when it has been performed by three-point bending. Cu-rich and Zr, Fe-rich zones have been found in the deformed BMG. The intensity of β-relaxation and the free volume are increased after the deforming process. The deformed BMG presents a work-hardening like behavior and it has a larger compressive plasticity than the undeformed BMG, which is attributed to the microstructural heterogeneity and rejuvenation by the deformation.
