| 摘 要： | 采用高压DTA方法，测定了Cd-Sn-Zn三元系中xCd=20 at.%截面的高压垂直截面相图，实验压力为0，0.5，1.0，1.5 GPa。所得高压相图与常压相图比较，在p=1.5 GPa时低共晶点上移了大约35 K，共析组成在加压过程中几乎不变。这种变化趋势与理论计算的结果相图，所得高压相图的液相线与计算相图的一致。

| Abstract: | Several vertical sections of the phase diagrams of Cd-Sn-Zn ternary alloy system with a constant composition of Xcd= 0. 2 were determined by differential thermal analysis (DTA) at high pressures. Working pressures were 0,0. 5,1. 0, and 1. 5GPa. The eutectic temperature of the system increased by about 35K as the pressure going from atmospheric to 1. 5GPa, though the eutectoid composition changed little with pressure in the experiment. This tendency in temperature shifting coincides with the results of calculated phase diagrams. Experimental liquidus at 1. 5GPa tallies well with that of calculated results. |
