用Ｘ射线衍射分析、透射电镜等技术研究了几种不同热处理制度下Ｃｕ—６．３１Ａｌ—１８·４７Ｚｎ（ｗｔ％）合金试样的马氏体结构、有序畴尺寸及社度、有序度、亚结构，并计算了马氏体的能量．结果表明：试样经不同的热处理制度后，１８Ｒ１马氏体结构由Ｍ型变为Ｎ型，层错由基面变为非基面层错；有序畴衬度与热处理制度无关；马氏体有序度Ｓ越大，对应的能量越高，马氏体越不易稳定化。
The martensite structure, ordered domain size and social order of Cu-6.31Al-18.47Zn (wt%) alloy samples under several different heat treatments were studied by means of X-ray diffraction and transmission electron microscopy. Degrees, substructures, and calculated the energy of martensite. The results show that the structure of 18R1 martensite changes from M to N, and the stacking fault changes from basal to non-basal plane faults after different heat treatment regimes. The alignment of ordered domains is not related to heat treatment. The greater the degree of body ordering S, the higher the corresponding energy, the less stable the martensite is.
