Inducing secondary phase is one of effective means to improve the room temperature plasticity of amorphous alloy matrix composites. The amorphous alloys and their deformation characteristics were reviewed, and the fabrication process as well as mechanical properties of amorphous alloy matrix composites were summarized, including ex-situ particle/fiber reinforced, in-situ precipitated phase reinforced systems and Zr-based, Ti-based and Mg-based alloy systems. In addition, the latest developments on reinforcing phases and their fabrication process were introduced, including porous particles, shape memory phase, dealloying reaction in metallic melt, selective phase leaching process. Moreover, the microstructure, mechanical properties and optimization technologies of the above composites were expounded in detail, and the prospect was pointed out.
