采用X射线衍射、DTA差热分析和显微金相分析等方法研究了Au-Ag-Gd三元系相图的富Au-Ag区域(Gd≤33.3%;原子数分数,下同),测定了Au-Ag-Gd三元系部分相图的700℃部分等温截面.该截面上有6个单相区:(Ag,Au),Ag51Gd14,Ag2Gd,Au2Gd,Gd14Au51和GdAu6;9个两相区:Ag51 Gd14+(Ag,Au),Ag51 Gd14+Ag2Gd,Ag2Gd+Gd14Au51,(Ag,Au)+Au2Gd,Ag2Gd+Au2Gd,(Ag,Au)+Gd14Au51,Ag51Gd14+Au2Gd,Gd14Au51+GdAu6和(Ag,Au)+GdAu6;4个三相区:(Ag,Au)+Gd14Au51+Au2Gd,Ag51 Gd14+(Ag,Au)+Au2Gd,Ag51Gd14+Ag2Gd+Au2Gd和(Ag,Au)+GdAu6+Gd14Au51.在该成份区域未发现新的三元化合物.
