摘要
虽然Ｃｕ—Ｚｎ—Ａｌ和Ｃｕ—Ａｕ—Ｚｎ合金中的母相已知为ＤＯ３或Ｌ（２１）结构，但通过通道增强微分析原子定位法（ＡＬＣＨＥＭＩ），可以检测Ｃｕ—Ｚｎ—Ａｌ合金的母，马氏体相和Ｃｕ—Ａｎ—Ｚｎ合金的母相、马氏体、贝氏体相中的原子配置结果表明．马氏体相中原子配置与母相是完全一样的，但Ｃｕ—Ｚｎ—Ａｌ合金中时效马氏体和Ｃｕ一Ａｎ—Ｚｎ合金中贝氏体与母相不同。
The atomic configuration in the parent and martensite phases of Cu-Zn-Al alloys and in the parent, martensite and bainite phases of Cu-An-Zn alloys have been examined by the atom location by channelling enhanced microanalysis (ALCHEMI) method, although the parent phase of both the alloys has been known to be ordered into the DO3 or L(21) type. As a result, the atomic configuration in the martensite phase was clearly verified to be the same as that in the parent phase in both the alloys, but that in the aged martensite of Cu-Zn-Al alloys and the bainite of Cu-An-Zn alloys to not be the same. These results of the ALCHEMI measurements will be described in the present paper.
