英文摘要：

A series of Gd-Sn-Te system alloys are prepared by powder metallurgy method. Phase composition and phase transition of the samples were investigated by X-ray diffraction （XRD） and differential thermal analysis （DTA）. The results show that the composition and microstructure of the samples are uniform. Gd element can be uniformly doped into the alloy system, and the required equilibrium state is obtained. Therefore ,this method can satisfy the demand of phase diagram and phase structure study.
