Abstract

Ni–Al–Co alloy with the composition 45 wt % Ni + 41 wt % Co + 14 wt % Al has been prepared for the first time by aluminothermic reaction. The phase composition of the synthesized alloy comprises a cubic (Ni,Co)₃Al solid solution of cobalt in nickel aluminide (γ'-phase) and a tetragonal (Ni,Co)₃Al phase. The formation of the tetragonal structure of (Ni,Co)₃Al is due to a martensitic transformation of a supersaturated initial structure in grains of the cubic (Ni,Co)₃Al phase. The intragranular microhardness of the synthesized alloy is 6500 MPa. The alloy has soft magnetic properties, with the highest magnetization of 27 emu/g in a magnetic field of 10 kOe.

Ni-Al-Co 系统中高温铝热合成产物的多态性

摘要--首次通过铝热反应制备了成分为 45 wt % Ni + 41 wt % Co + 14 wt % Al 的镍-铝-钴合金。合成合金的相组成包括钴在镍铝化物中的立方（Ni,Co）3Al 固溶体（γ'-相）和四方（Ni,Co）3Al 相。(Ni,Co)3Al四方结构的形成是由于立方(Ni,Co)3Al相晶粒中的过饱和初始结构发生了马氏体转变。合成合金的晶内显微硬度为 6500 兆帕。该合金具有软磁特性，在 10 kOe 磁场中的最高磁化率为 27 emu/g。
