采用X射线衍射和金相显微镜分析方法研究了含0—25at.-%Gd的Ag-Pd-Gd三元系,作出了该体系部分相图的750℃等温截面和室温截面。发现在该二截面上都分别存在三个单相区、三个两相区和一个三相区。
The Ag-Pd-Gd ternary system containing 0-25at .-% Gd was studied by means of X-ray diffraction and metallographic microscope. The isothermal section and room temperature section of 750 ℃ were obtained. It is found that there are three single-phase zones, three two-phase zones and one three-phase zone respectively on the two cross sections.
