Abstract

A kind of in-situ Ti-based metallic glass matrix composite containing ductile dendrites was fabricated. Quasi-static and dynamic compression behaviors of the composite were investigated. Upon quasi-static loading, the composite exhibits ultrahigh strength, accompanied by macroscopic plasticity. In micro, multiple shear bands on the lateral surface and abundant droplets on the fracture surface characterize the plasticity of the composite. However, all the samples fracture with brittleness due to the insufficient time to generate multiple shear bands. The different deformation and fracture mechanism of the composite upon quasi-static and dynamic loading are interpreted.
