In situ study of the evolution of atomic strain of bulk metallic glass and its effects on shear band formation

Abstract

The tensile behavior of TiZrNiCuBe metallic glass was studied using synchrotron X-ray diffraction and scanning electron microscopy. Shear band formation was carefully controlled by the introduction of a stress gradient due to a semi-circular notch. Micro- and atomic-level strains were calculated by the Q-space method and pair distribution function analysis, respectively. The atomic-pair strains for the area near the notch increase exponentially at the final deformation stage. This can be directly linked to the shear-induced dilatation resulting from the shear band formation. © 2013 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
