摘要
利用真空电弧炉熔铸AlxCrCuFeNi(x=0.5,1.0,1.5,2.0)高熵合金。金相显微镜与X射线衍射分析表明,AlxCrCuFeNi高熵合金具有面心立方(fcc)和体心立方(bcc)结构,合金的铸态组织是典型的树枝晶。Al促进AlxCrCuFeNi合金的bcc结构的形成,而bcc的形成使AlxCrCuFeNi合金的硬度得到提高。
The AlxCrCuFeNi (x=0.5,1.0,1.5,2.0) high-entropy alloy was prepared by the arc melting and casting method. The effect of Al content on microstructure and hardness of the alloy was investigated by microscope and vichers hardness testing, X-ray diffractometer. The results show that the alloy exhibits simple fcc and bcc structure, its microstructure as-cast is typical dendrite. Al enhances the formation of the bcc phases, which significantly increases the hardness of the alloy.
