In this study, the Pandat software was used with the PanHEA database. There were six points could form high-entropy alloys in the Al, Co, Fe, Ni, and Ti five-element system were calculated and selected for experiments. From the analysis of various results, it can be known that Alloy 2 (Al-31 at.% Co-33 at.% Fe-24 at.% Ni-6 at.% Ti) exhibits a single-phase solid solution structure, while the other five alloys is mainly composed of FCC phase and contains a relatively small amount of one or two other phases (L12, B2, H_21). The results obtained from the experiments are all in line with the calculated predictions. The experimental analysis of alloy hardness and corrosion was further carried out, and stainless steel 304 was used as a control group. The alloys in this study all have higher hardness than stainless steel 304, but are more corrosive and have a faster corrosion rate.
