利用Ｘ射线衍射强度分析、透射电镜观察、相变点测量等方法研究了空冷淬火态Ｃｕ１８Ｚｎ１４Ａｌ合金马氏体结构及其稳定化现象。认为该合金空冷淬火可获得长程有序完全的Ｍ１８Ｒ马氏体，其有序组态为Ａｌ原子与Ｃｕ原子、Ｚｎ原子与Ｃｕ原子两种近邻（ｎｎ）有序（Ｋ＝偶，Ｈ＋Ｋ／２＝奇），以及产生Ｋ＝奇的衍射中Ａｌ原子与Ｚｎ原子次近邻（ｎｎｎ）有序。其基面原子分布为：Ⅰ—１４２５Ａｌ＋１１２５Ｃｕ、Ⅱ—Ｃｕ、Ⅲ—１８２５Ｚｎ＋７２５Ｃｕ。与此相对应，该合金相应为Ｈｅｕｓｌｅｒ结构。该合金在充分有序化的条件下仍存在马氏体稳定化。
The structure and stabilization of martensite in air-quenched Cu18Zn14Al alloy were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM) and phase transition point measurement. The results show that M18R martensite with long-range and orderly structure can be obtained by air-cooled quenching. The ordered structure is composed of Al atoms and Cu atoms, and Zn and Cu atoms are near (nn) ordered (K = even, H + K / 2 = Odd), and the nearest neighbor (nnn) of the Al atom to the Zn atom in the diffraction producing K = odd. The atomic distribution of its base surface: Ⅰ-1425Al + 1125Cu, Ⅱ-Cu, Ⅲ-1825Zn + 725Cu. Correspondingly, this alloy corresponds to the Heusler structure. The alloy still has martensite stabilization under fully ordered conditions.
