【摘要】 用热分析法研究了Al-Cu-Ag体系中Al-Al₂Cu-Ag₂Al角的液相限。本体系属共晶类型。三元共晶点的温度为500℃,组成（wt-%）分别是Al（40）,Cu（19.3）,Ag（40.7）。更多还原

【Abstract】 Thermal analytical study of the liquidus of Al-Al₂Cu-Ag₂Al corner in the phase diagram of Al-Cu-Ag system was made if possible to ascertain a suitable fillet metal in Al brazing at medium temperature range. The system belongs to a eutectic type. The composition of the eutectic point is: Al 40.0%, Cu 19.3%, Ag 40.7% and its temperature 500℃. A phase diagram has been figured.更多还原
