AI Technical Summary

Technical Problem

Traditional metal matrix composites suffer from low ductility due to the use of hard ceramic reinforcement, which limits their application range. Existing technologies are unable to effectively improve the overall mechanical properties of composite materials.

Method used

By adding the MAX phase as a binder phase to the metal matrix composite material, and utilizing the nanolayered structure and in-situ reaction of the MAX phase to form a new reinforcing phase, combined with mechanical ball milling and powder sintering processes, a MAX-transition metal carbide/nitride/boride composite material was prepared.

Benefits of technology

It significantly improves the hardness, flexural strength, fracture toughness and high temperature resistance of composite materials, simplifies the preparation process, is suitable for mass production, and avoids the failure caused by the softening of traditional metal binder phases at high temperatures.
