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.
