Research on Effects of Tempering Process on Microstructure and Corrosion Resistance of AlFeCrCoCu High-entropy Alloy AITranslate
Abstract AITranslate
The microstructure was studied of AlFeCrCoCu high-entropy alloy prepared by vacuum arc melting.Effects were investigated of tempering process on alloy microstructure,hardness and corrosion resistance in 3.5% NaCl solution.The results show that the alloy has dendrite microstructure,the dendrite is Al,Fe,Cr,Co-rich BCC phase and intergranular microstructure is Cu-rich FCC phase.Alloy melting point is about 1 380 ℃,and intergranular Cu-rich phase begins phase transition at about 1 050 ℃.With the increase of tempering temperature,the grains begin to grow up until develop into coarse grains at about 1 000℃.The alloy exhibits a superior resistance to temper softening.Electrochemical test results show that the alloy has better corrosion resistance than 304 stainless steel,and 800 ℃ temper microstructure has the highest corrosion resistance.
