Ti-based bulk metallic glass composites combine the microstructural characteristics of titanium alloys and bulk metallic glasses, which not only achieve high strength, but also solve the key problem of room temperature brittleness of traditional bulk metallic glasses. Therefore, they are considered as a new type of lightweight, high-strength and ductile structural materials with great potential. As a new material, a series of key scientific technological problems need to be solved from basic research to large-scale engineering applications. The mechanical properties of Ti-based bulk metallic glass composites are reviewed in this paper. At the same time, opinions and future research directions are proposed for the problems existing in the current research.
