摘要： 用穆斯堡尔谱及X射线衍射技术研究不同Fe含量的Ni-Fe合金电沉积层的结构.当Fe含量小于46at％时,该合金层为γ相(F.C.C.);Fe含量大于63at％时为α相(B.C.C.);在46at％～63at％之间两相共存.Fe含量为25at％左右时,存在部分有序的Ni3Fe结构;Fe含量为35at％～46at％时,出现富铁相γ'(F.C.C.).由于富铁相的存在,使Fe含量在约46at％时出现α相,而在冶炼的Ni-Fe合金中,只有当Fe含量达70at％时才出现α相.γ相合金的晶格参数一般随Fe含量的增加而增大,Fe含量在～25at％时,因有序的Ni3Fe存在使晶格参数略为减小.当α、γ相共存时,γ相合金的晶格参数基本不变.

Abstract: Electrodeposited Ni-Fe alloys with different Fe contents have been studied by means of Mossbauer spectroscopy and X-ray diffraction technique.Those deposits containing less than 46 at% Fe, were identified as γ-phase, those containing 46 at%-63 at% Fe as α+γ phases, and those containing more than 63 at% Fe as γ-phase.Partially ordered Ni3Fe was found to exist in deposits containing about 25 at% Fe and Fe-rich phase in the range of 35 at%-46 at% Fe.In general, the lattice parameters of γ-phase increase with Fe content increasing.However, in the deposits containing about 25 at% Fe(20 at%-30 at%) the lattice parameters decrease slightly with the increasing of Fe content, which is due to the presence of partially ordered Ni3Fe in the deposits.The lattice parameter is almost constant in deposits with Fe content from 46 at% to 63 at%.
