Abstract

The solid solubility of Sn in gamma 1 has been studied by examining a series of gamma 1 samples containing 0.25-2.0 wt% Sn by scanning electron microscopy and energy-dispersive X-ray analysis. It has been observed that the addition of Sn to gamma 1 leads to the formation of mainly an intergranular Sn-Hg compound. On the basis of this observation it has been concluded that the solubility of Sn in gamma 1 is virtually nil.

摘要

通过扫描电子显微镜和能量色散X射线分析，研究了一系列含0.25 - 2.0 wt%锡的γ1样品，以此来探究锡在γ1中的固溶度。据观察，向γ1中添加锡主要会导致形成一种晶间锡汞化合物。基于这一观察结果，得出结论：锡在γ1中的溶解度几乎为零。
