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，本文叙述ＡＬＣＨＥＭＩ测定的结果 Although the parent phases in Cu-Zn-Al and Cu-Au-Zn alloys are known as DO3 or L (21) structures, channel-enhanced microanalysis atomic localization (ALCHEMI) The results of the atomic configuration in the parent phase, the martensite phase and the parent phase, the martensite and the bainite phase of the Cu-An-Zn alloy are shown. The arrangement of atoms in the martensite phase is exactly the same as that of the parent phase. However, the aged martensite in the Cu-Zn-Al alloy and the bainite in the Cu-An-Zn alloy are different from the parent phase. The results of the ALCHEMI measurement
