| Abstract: | High-entropy alloys, one of the three breakthroughs of metallic materials field in recent years, dash out the cage of traditional design concept about alloys, and could produce alloy materials with high strength, excellent wear resistance and anti-corrosion in proper proportion. The four elements of Fe, Co, Cr, Ni have been widely applied in the high-entropy alloys systems and gained a number of outstanding achievements. This paper demonstrate the feature of structures and transitions in CoCrFeNi-M high-entropy alloy systems. Furthermore, the effect of alloying elements on as-cast high-entropy alloys are illustrated, the heat treatment processes of high-entropy alloys are discussed. Finally, the current research status and existing problems of high entropy alloys are summarized. |
