摘　　要：应用扫描电镜和X-射线衍射测试,对在Ni-Cr-Mo-Cu合金中进行Fe掺杂的合金进行了微观组织观察和量化分析,表明该合金形成了基体和弥散相两种组织。使用Materials studio7.0材料计算软件对主要组织的超晶胞进行了结合能的计算,最终确定出了基体和弥散相的成分组成。The microstructure observation and quantitative analysis of alloying behavior of Ni-Cr-Mo-Cu alloy adding Fe was carried out by SEM and X-ray diffraction test. Then, the phase components of all the alloys was base metal and dispersed phase. The binding energy of supercell in main microstructure was calculated by material calculation software Materials studio7.0. Then, the component of matrix and dispersion phase was ensured.
