摘要

The information of phase diagram for the Sm-Zr system is deficient. A diffusion couple and two alloys in Sm-rich side of Sm-Zr system were prepared. The phase equilibrium in the alloys at 800 and 900°C were determined by scanning electron microscopy, equipped with energy dispersive X-ray spectroscopy (SEM-EDS) and X-ray diffraction(XRD). The results show that a peritectic reaction exists in the Sm-rich end. The solubility of Sm in (Zr) was detected to be about 2.4 at.% at 800°C and 2.7 at.% at 900°C. The solubility of Zr in (Sm) is negligible. No binary compound is detected in the XRD patterns in all samples.
