A Ti/Ti-based-metallic-glass interpenetrating phase composite (IPC) was prepared by infiltrating the Ti-34.3 Zr31.5Ni5.5Cu5Be23.7 melt into the porous Ti skeleton. Porous Ti limits the shear band (SB) propagation and promotes the SB multiplication, leading to the improved ductility. Moreover, the interpenetrating phase structure shows a mutual reinforcement effect for both amorphous and crystalline phases, making IPC possess higher strength than that calculated by the models held for the conventional composites. This finding will suggest a new way for preparing composites with high strength and ductility.
