摘要
运用描述近程有序结构的"团簇加连接原子"方法,建立了Au-Cu合金的稳定局域结构模型,进而解析了具有特殊性能的成分点,其中包括ASTM手册中列出的3种钎料BAu-11(50Au-50Cu)、BAu-1(37.5Au-62.5Cu)和BAu-2(80Au-20Cu)。结果表明,特殊性能成分金铜合金,具有简单的满足团簇式的成分规律,反映着固溶体近程有序本质结构。
The stable local structure model for Au-Cu alloys was established using the ＂cluster and glue atom＂approach that suits for short-range-order structure description. All the composition points with special properties were thus interpreted,including three filler metals listed in the ASTM handbook such as BAu-11（ 50Au-50Cu）,BAu-1（ 37. 5Au-62. 5Cu） and BAu-2（ 80Au-20Cu）. The results show that the Au-Cu alloys having special properties satisfy simple cluster formula composition rules that reflect the short-range-order nature of solid solutions.
