A Ti-based bulk metallic glass composite with excellent tensile properties and significant work-hardening capacity

摘要

A new Ti-based BMGC with excellent tensile plasticity and significant work-hardening capacity was successfully developed. The microstructure, mechanical behaviors and toughening mechanisms were investigated in details by SEM, XRD, TEM and Nano-indentation. It is found that the stress-induced martensitic transformation from beta to alpha '' phase and the mechanical twinning in the alpha '' phase combined to account for these mechanical behaviors. The current work offers a new perspective for developing in situ dendrite reinforced BMGCs with improved homogeneous ductility and significant work-hardening capacity. (C) 2018 Elsevier B.V.
