摘要：
The AlxFeCrCoCuV (x=0, 0.5, 1.0) high-entropy alloys were fabricated by non-consumable vacuum arc melting furnace, the characteristics including microstructure, hardness and wear properties were examined by XRD, SEM, EDS and DSC. The results show that with the addition of aluminum, Al0.5CrFeCoCuV and Al1.0CrFeCoCuV alloys from single BCC phase of FeCrCoCuV to a transition duplex FCC/BCC phase; the hardness of Al1.0CrFeCoCuV alloy is larger than Al0.5CrFeCoCuV alloy. The alloys show adhesive wear behaviors, the wear-resisting performance of the alloys is proportional to its hardness. With the increase of friction time, the three alloys generate a layer of oxide on the surface and attach to the friction surfaces to improve the wear resistance. © 2016, Beijing Institute of Aeronautical Materials (BIAM).
