Experimental determination of phase equilibria in the Sn-Zn-Sb system
首发时间:2015-05-04
Abstract:The phase equilibria of the Sn-Zn-Sb ternary system at 400 oС and 500 C were experimentally determined by electron probe microanalyzer (EPMA), X-ray diffraction (XRD) and differential scanning calorimetry (DSC). In this study, the ternary compound of (Zn,Sn)Sb is confirmed at 400 C and 500 C. Additionally, a liquid phase region is found at 400 C with composition ranges of 9.09 ~ 12.86 at.% Zn and 31.47 ~ 34.22 at.% Sn, which becomes a prolongation of the main liquid as the temperature is raised to 500 C.

Sn-Zn-Sb三元合金相平衡的实验研究
摘要:本研究通过背散射电子(BSE),电子探针显微分析仪(EPMA)、差示扫描量热分析(DSC)和X射线衍射(XRD)等方法测定了Sn-Zn-Sb三元体系在400℃与500℃的成分范围内的相平衡关系.实验结果表明:三元化合物(Zn,Sn)Sb被证实能稳定存在于400 ℃与500 ℃.此外,在400 ℃温度下发现一处液相区域,其成分范围在9.09 ~ 12.86 at.% Zn和31.47 ~ 34.22 at.% Sn之间.当温度上升到500 ℃时,该液相区域与富Sn侧液相合并一起.
