摘要: 采用X射线衍射和金相显微分析方法研究了Gd-Pd-Pt三元系中含0—33at。-%Gd的区域,测定了它的室温和700℃等温截面。在该二截面上都分别存在5个单相区(固溶体Pd(Pt)或Pt(Pd),GdPd_3,GdPd_2,GdPt_2和GdPt_5),7个二相区(Pd(Pt)+GdPd_3,Pd(Pt)+GdPt_?,GdPd_3+GdPd_2,GdPd_2+GdPt_2,GdPt_2+GdPd_3,GdPt_2+GdPt_5和GdPd_3+GdPt_5),3个三相区(Pd(Pt)+GdPt_5+GdPd_3,GdPt_5+GdPd_3+GdPt_2和GdPd_3+GdPd_2+GdPt_2)。未发现任何新的三元金属间化合物。

Abstract:The room temperature and 700℃ isothermal sections for the region containing0--33 at. -%Gd of Gd-Pd-Pt ternary system phase diagram have been determined by X-raydiffraction analysis and optical microscopy. Both sections consist of 5 single phase regions-Pd(Pt) or Pt(Pd), GdPd_3, GdPd_2, GdPt_5 and GdPt_2; 7 bi-phase regions-Pd(Pt)+GdPd_3, Pd(Pt)+GdPt_5, GdPd_3+GdPd_2, GdPd_2+GdPt_2, GdPt_2+GdPd_3, GdPt_2+GdPt_5 and GdPd_3+GdPt_5; and 3tri-phase regions-Pd(Pt)+GdPt_5+GdPd_3, GdPt_5+GdPd_3+GdPt_2 and GdPd_3+GdPd_2+GdPt_2 respe-ctively. No any ternary intermetallic compound is found.
