Ag-Pd-Gd三元系(Gd≤25at-%)部分相图

ROOM TEMPERATURE AND 750℃ ISOTHERMAL SECTIONS OF Ag-Pd-Gd TERNARY SYSTEM (Gd≤25 at.-%) PHASE DIAGRAM

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 room temperature section and the isothermal section at 750℃ ofthe Ag-Pd-Gd ternary system containing 0--25at.-% Gd are constructed by X-raydiffraction analysis and optical microscopy. Both sections consist of 3 single-, 3 bi-nary-and 1 ternary-regions respectively.
