Abstract
Phase transformation behaviors can modulate the stress distribution under loading and enhance the plasticity and work hardening ability of amorphous alloy composite. Effect of pre-plastic deformation on the phase transformation kinetics and the mechanical properties of the TiZr-based amorphous alloy composite were studied systematically in the current work. The plasticity of the composites was improved by lateral pre-compression deformation and pre-tensile deformation. However, the plasticity reduced after axial pre-compression deformation. These results were attributed to the distinguish of the directions between the pre-existing shear bands formed during pre-plastic deformation and new developed shear bands during the final compression, which can favor the severe interaction of shear bands.
