A Ti/Ti-based-metallic-glass interpenetrating phase composite (IPC) was prepared by infiltrating the Ti34.3Zr31.5Ni5.5Cu5Be23.7 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.
