摘要：AlxCrFe1.5Ni0.5 alloys (x=0.15, 0.2, 0.3, 0.4) were prepared by arc melting pure elements under argon atmosphere. All the AlxCrFe1.5Ni0.5 alloys present a single bcc solid solution crystal structure. Because of the common precipitation strengthening effect of lamellar precipitates and equiaxed particles, the hardness of the Al0.15CrFe1.5Ni0.5 alloy is quite high, reaching 443.2 HV. Microstructures of the AlxCrFe1.5Ni0.5 alloys (x=0.2, 0.3, 0.4) are very simple. The crystal boundary is quite straight. With the content of Al increasing from 0.2 to 0.4, the hardness of the alloy increases from 303.8 to 450.1 HV through the solution strengthening effect of the Al atom.
