Research Progress on Forming and Tribological Properties of Particle Reinforced High Entropy Matrix Composites

High entropy alloy is a new concept of multiple alloy developed for the last decade or so, which has many advantages in physical, chemical and mechanical properties. In order to solve the limitations of high entropy alloy in the application of friction and wear and improve the comprehensive mechanical properties, composite materials with high entropy alloy as matrix and reinforced phase (HEAMCs) have become a hot topic in metal field. Based on this, this work summarizes the preparation and forming methods of different HEAMCs according to the research status, and analyzes the advantages and disadvantages of the preparation methods of powder metallurgy, smelting and laser cladding in detail. In this study, the strengthening mechanisms of HEAMCs in nanocrystalline strengthening and the second phase co-strengthening are summarized. Then, the studies on the friction and wear properties of HEAMCs at room temperature and high temperature are summarized, respectively. Finally, the current challenges and future development of HEAMCs are discussed and prospected.
