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。
X-ray diffraction and metallographic analysis of the Gd-Pd-Pt ternary system containing 0-33at. -% Gd region, measured its room temperature and 700 ℃ isothermal cross section. There are five single-phase regions (solid solution Pd (Pt) or Pt (Pd), GdPd 3, GdPd 2, GdPt 2 and GdPt 5), 7 two-phase regions GdPt_5 + GdPt_5, GdPd_3 + GdPd_2, GdPd_2 + GdPt_2, GdPt_2 + GdPd_3, GdPt_2 + GdPt_5 and GdPd_3 + GdPt_5), three threephase regions (Pd (Pt) + GdPt_5 + GdPd_3, GdPt_5 + GdPd_3 + GdPt_2 and GdPd_3 + GdPd_2 + GdPt_2). No new ternary intermetallics were found.
