通过电阻率测量、硬度测试、光学显微镜观察和透射电子显微镜观察，研究了添加铬对低金含量合金晶内和晶界反应的影响。铬的加入促进了晶内反应，而抑制了晶界反应。随着铬含量的增加，奥铜-L型有序相在晶内的形成被加速，且其T-T-T曲线向更高的温度和更短的时间移动。
The effect on grain interior and grain boundary reactions by Cr addition to low gold content alloys were investigated by electric resistivity measurements, hardness tests, optical microscopic observations, and TEM observations. The grain interior reactions were accelerated by the chromium addition while grain boundary reactions were retarded. The formation of AuCu l type ordered phase in the grain interior was accelerated, and the T-T-T curve of AuCu l type ordered phase shifted to higher temperatures and shorter times with increasing chromium content.
