Abstract: The mechanisms of shear banding in Zr-based bulk metallic glasses (BMGs) containing dendrite phase such as β-Zr2Cu are numerically investigated using the phase-field simulation approaches. The growth of dendrite is simulated based on Elder's solidification theory. The interactions between the shear bands and the dendrites are studied using the phase-field model for shear banding in BMGs. It is found that the properties of dendrites such as the rotation angle representing their dispersion patterns and their fracture energy significantly affect the branching, multiplication and detour of shear bands, which result in the improved ductility of the composites. The simulation evaluates quantitatively the properties of dendrites that determine the features of shear banding in the composites.
