    Abstract:

    AlxTiCrMnCu (x=0, 0.25, 0.5, 0.75, 1.0) high entropy alloys were prepared by laser deposition. The XRD、SEM and corrosion electrochemical testing methods were used to investigate the effect of Al on the microstructure and properties of AlxTiCrMnCu alloys. The results show that, with the increase of Al addition, phases of AlxTiCrMnCu alloys change from simple FCC and HCP1 solid-solutions to single HCP2 solid-solution. The microhardness of AlxTiCrMnCu alloys increases gradually with the increase of Al addition. The corrosion resistance of AlxTiCrMnCu alloys in 3.5% NaCl solution increases firstly and then decreases with the increase of Al addition. The optimum corrosion resistance can be obtained when x=0.25.
