Abstract Intermetallic compounds and micro-structures in Ni–Mn–In alloy system were investigated with transmission electron microscopy, selected-area and nano-beam electron diffraction, and energy-dispersive x-ray spectroscopy. Together with two types of Heusler phases, a decagonal quasicrystalline phase and a structurally related crystallite were found in the Ni–Mn–In system. As is well-known, most of the decagonal quasicrystals are aluminum-based intermetallic phases. It is interesting to investigate the aluminum-free decagonal quasicrystalline phase as a new member of the quasicrystal family. Structural characterization was carried out on the decagonal quasicrystalline phase and the crystalline approximant in the Ni–Mn–In alloy system.

Ni-Mn-In Heusler合金体系中的准晶相和结晶近似

摘要 采用透射电子显微镜、选区和纳米束电子衍射以及能量色散X射线光谱研究了Ni-Mn-In合金体系中的金属间化合物和微观结构。与两种类型的 Heusler 相一起，在 Ni-Mn-In 系统中发现了十边形准晶相和结构相关的微晶。众所周知，大多数十边形准晶是铝基金属间相。研究无铝十边形准晶相作为准晶家族的新成员很有趣。对 Ni-Mn-In 合金体系中的十边形准晶相和晶体近似物进行了结构表征。
