用差热分析法、X射线衍射法和金相显微镜观察法研究了Gd-In二元系合金相图,实验证实了有六个中间相:Gd_3In,Gd_2In,Gd_5In_3,Gdln,Gd_2In_3和Gdln_3,有五个共晶转变,分别与～12at％In(共晶温度988℃),～30.5at％In(1151℃),～38.5at％In(1114℃),～64.5at％In(1010℃)以及100at％In(156℃)处退化了的共晶点相对应,包晶反应形成的化合物Gd_2In_3的分解温度T_(per)=1104℃,包析反应2Gd_2+GdIn Gd_5In_3发生在37.5at％In和1071℃,没有发现In在Gd中和Gd在In中有可觉察的固溶度,这些中间相的晶体结构没有进行测量。
The phase diagram of Gd-In binary system alloy was studied by DTA, X-ray diffraction and metallographic microscope. The experiment confirmed that there are six mesophases: Gd_3In, Gd_2In, Gd_5In_3, Gdln, Gd_2In_3 and Gdln_3 Five eutectic transformations were performed with ~ 12 at% In (eutectic temperature 988 ° C), ~ 30.5 at% In (1151 ° C), ~ 38.5 at% In (1114 ° C), ~ 64.5 at% In The decomposition temperature of the compound Gd_2In_3 peritectic reaction was 1104 ℃, and that of the 2Gd_2 + GdIn Gd_5In_3 inclusion reaction was 37.5at% In and 1071 ° C, no detectable solid solubility of In in Gd and Gd was found in In, and the crystal structure of these mesophases was not measured.
