中文摘要: 采用放热感应熔炼工艺，用Ni，Al和Fe合成NiAl-Fe。借助XRD进行相分析，对不同Fe含量的合金进行室温塑性、压缩性能和硬度测试；利用SEM对试样断口进行观察。结果显示，采用放热感应熔炼法可以制备铸态NiAl-Fe，向NiAl中添加大量Fe元素引入塑性的第二相，使得合金的室温塑性、压缩性能、硬度等得到提高。热处理可以进一步提高合金的机械性能。
Abstract:Ni,Al and Fe reaction by Exo-Melt TM process,NiAl-Fe intermetallic alloy was obtained.The phase is studied by XRD,room-temperature ductility,compress properties and hardness were investigated and the fracture surfaces were observed by SEM.The experimental results show this alloy has higher room-temperature ductility,compress properties and hardness with the addition of Fe and the heat treatment could improve the mechanical properties of NiAl-Fe.
