The application and research status of MAX reinforced metal matrix composites

The Mn+1AX_n (referred to as MAX) is a ternary layered material. MAX can be introduced into metallic materials as a strengthening phase to form metal-based composite materials. These composites exhibit excellent mechanical properties and tribological properties, thereby laying a theoretical basis for extending their applications. Here, the application and its performance of MAX phase are introduced. The interface effect on conductivity and mechanical properties of MAX phase reinforce metal matrix composites is summarized. The tribological behaviors of MAX reinforced metal matrix composites are overviewed. Meanwhile, the wear mechanism of the MAX phase as a reinforcing phase in synergistic friction, single phase friction, and high temperature friction is elaborated. Finally, the outlook of MAX phase in future research prospected is described.
