An inter-metallic phase in the Al-Mn-Ni system crystallizing in space group (No. 63) and refined formula AlMnNi (called the ' phase) has been synthesized by high-temperature sinter-ing of a mixture with initial chemical composition AlMnNi. In comparison with the structure model of the previously reported phase with composition AlMnNi [Robinson (1954 ▸). . , 494-497], there are two mutually exchanged Mn and Ni sites together with one positionally disordered Al site [occupancy ratio 0.811 (8):0.121 (7)] and one partially occupied Mn site [s.o.f. 0.677 (5)] in the current structure model of the ' phase.
通过对初始化学组成为AlMnNi的混合物进行高温烧结,合成了Al-Mn-Ni体系中一种在空间群(第63号)中结晶且化学式为AlMnNi(称为“γ相”)的金属间相。与之前报道的组成为AlMnNi的γ相结构模型[罗宾逊(1954▸)......,494 - 497]相比,在当前的γ相结构模型中,有两个相互交换的Mn和Ni位点,以及一个位置无序的Al位点[占有率0.811(8):0.121(7)]和一个部分占据的Mn位点[占有率0.677(5)]。
