英文摘要	The as-cast FeCrCoNiMn high-entroy alloy was prepared by arc furnace in vacuum and the alloy was immersed in the molten aluminum at 700 with different times (0-1 h). Microstructure evolution and phase formation mechanism in HEA/Al interface were investigated. The results showed that when the high-entroy alloy was immersed in the molten Al, a region with complicated microstructure including the reaction layer with Al-rich intermetallic Al86Cr13.5Fe6.5, Al86Mn14, Al3Ni and Al9Co2 phase at the HEA/Al interface, bulk phase containing high concentration of Cr and Mn, lamellar precipitate and net structure in solidified Al could be formed. At the beginning of the hot dipping, the formation and growth of the reaction layer was controlled by dissolving and exfoliation of high-entroy alloy elements, meanwhile the layer was mainly located in Al side and migrated rapidly. After the reaction layer is formed, the layer thickness increased with the increase of the dipping time. When dipping time is more than 10 min, the thickness of the reaction layer was basically maintained at about 20 μm and the migration rate of the reaction layer became slowly. © 2016, Materials Review Magazine.
