Dynamic compressive response of a dendrite-reinforced Ti-based bulk metallic glass composite

Dynamic compressive response of a dendrite-reinforced Ti-based bulk metallic glass composite is investigated. Strain rate dependencies of the max strength and strain energy density are illustrated. The inherent mechanisms are revealed by studying the dynamic deformation behaviors at lower and higher strain rates. Under high-rate loading, the deformation and fracture of the soft crystalline dendrites and the hard amorphous matrix are characterized, respectively. Then, their contributions to the failure of the composite material are discussed. Finally, the dynamic damage efficiency of the composite material is addressed.
