用差热分析法测定了Ag-Cu-Bi系的液相限,共研究了12个多温截面。三元低共熔点的组成为Ag(5.0)-Cu(0.5)-Bi(94.5)at.-％,温度为285℃。Ag-Cu,Ag-Bi,Cu-Bi二元系液相限均经重复测定。
The liquid phase limit of Ag-Cu-Bi system was determined by DTA, and a total of 12 multi-temperature cross-sections were studied. The composition of the ternary eutectic point is Ag (5.0) -Cu (0.5) -Bi (94.5) at .-% at a temperature of 285 ° C. Ag-Cu, Ag-Bi, Cu-Bi binary system liquid phase limit were determined repeatedly.
