摘要: 本文用X射线衍射及差热分析方法测定了Gd-Ni二元系合金相图。在这个二元系中,观察到如下9个金属间化合物:Gd3Ni(735℃包晶分解),Gd3Ni2。(690℃包晶分解),GdNi(1280℃同成分熔化),GdNi2(1010℃包晶分解),GdNi3(1110℃包晶分解),Gd2Ni7(1200℃包晶分解),GdNi4(1270℃

Abstract: The Gd-Ni binary system has been reinvestigated by X-ray diffraction method and differential thermal analysis. The phase diagram has been determined. In this system, the following nine intermetallic compounds were found: Gd3Ni (decomposes at 735℃), Gd3Ni2 (decomposes at 690℃), GdNi (M. P. 1280℃) GdNi2 (decomposes at 1010℃), GdNi3(decomposes at 1110℃), Gd2Ni7(decomposes at 1200℃), GdNi4(decomposes at 1270℃), GdNi5(M. P. 1480℃) and Gd2Ni17(decomposes at 1285 ℃). Three eutectics occur: Gd3Ni-Gd3Ni2(635℃, ～32 at% Ni), GdNi2-GdNi2(880℃ ～56 at% Ni) and Gd2Ni17-Ni(1275℃, ～95 at Ni). Neither Go in Ni nor Ni in Gd shows any detectable solid solubility.
