Abstract High entropy alloys (HEAs) is a new kind of alloy with many properties superior to traditional alloys, and it has broad application prospects in many fields. At present, the research of high entropy alloys mainly focused on the mechanical properties, its high strength, high hardness, high wear resistance and corrosion resistance and other advantages manifest its potential as a structural material to serve under harsh conditions, but the current research of high entropy alloy is still in the exploratory stage. Researches on the mechanical properties of HEAs will be necessary and significant. In this paper, the effects of composition, preparation, heat treatment, and cold rolling on the microstructure and mechanical properties of HEAs are reviewed, and the application prospect of HEAs is also discussed.
