An aluminium-abundant AlMn/γ-brass-type inter-metallic with formula AlMn, which is isotypic with γ-AlCr and γ-AlV, was discovered by high-temperature sinter-ing of an Al/Mn mixture with initial composition AlMn. Structure analysis revealed that one special position (Wyckoff site 18 in space group ) is shared by Al and Mn, with refined site occupancy factors of 0.7 and 0.3, respectively. The present low-temperature AlMn-type phase crystallizes in the centrosymmetric space group (No. 166), rather than 3 (No. 160) as previously reported for the same inter-metallic characterized by TEM measurements [Zeng (2018 ▸). , 364-376].
通过对初始组成为AlMn的Al/Mn混合物进行高温烧结，发现了一种铝含量丰富的AlMn/γ-黄铜型金属间化合物，其化学式为AlMn，与γ-AlCr和γ-AlV同型。结构分析表明，一个特殊位置（空间群中的Wyckoff位置18）由Al和Mn共享，细化后的位置占有率因子分别为0.7和0.3。目前的低温AlMn型相结晶于中心对称空间群 （编号166），而不是如之前通过透射电镜测量表征的相同金属间化合物所报道的 3（编号160）[曾 （2018▸）。 ，364 - 376]。
