Abstract
Quasi-static and dynamic deformation behaviors of a dendrite reinforced metallic glass matrix composite: Ti58Zr16V10Cu4Be12 were investigated in this study. Upon quasi-static compression, the composite exhibits distinguished work-hardening capacity. The ultimate strength approaches 1970MPa, accompanied by the fracture strain of about 14.5%. The work-hardening of the ductile dendrites accounts for the macroscopic plasticity of the composite, and high strength of the glass matrix is responsible for the large ultimate strength of the composite. On the other hand, although the composites exhibit plasticity upon dynamic loading, the fracture strain decreases, due to the fact that there is not enough time for the initiation of multiple shear bands, leading to the decrease of the resistance to fracture. The ultimate strength and fracture strain of the present composites and some other in-situ and ex-situ composites upon dynamic loading reported by previous investigations are compared.
