摘　　要：A light-weight high-entropy alloy(LWHEA) Al_(20)Be_(20)Fe_(10)Si_(15)Ti_(35) has been developed to have unique mechanical properties and oxidation resistance. One major and two minor phases are observed in the as-cast microstructure. The density of the alloy is3.91 g cm^(-3), and its hardness is HV 911, which is higher than quartz. The hardness and hardness to density ratio are the highest of all light-weight alloys reported before. In addition, it has excellent oxidation resistance at 700℃ and 900℃, which far exceeds that of Ti-6 A1-4 V. Thus, the combination of properties is promising for high-temperature applications, which require light weight,wear-resistant and oxidation-resistant components. 关键词：硬合金 TI-6A1-4V 熵机械性质微观结构应用程序氧化高温度
