The microstructural evolution of tin-rich Sn–Bi alloys after the grain boundary wetting phase transition in the (liquid+β-Sn) two-phase region of the Sn–Bi phase diagram was investigated. Three Sn–Bi alloys with 30.6, 23, and 10wt% Bi were annealed between 139 and 215°C for 24h. ...
a thermodynamic model is formulated for the Sn-Bi-Ag phase diagram. Thermodynamic functions for the various phases obtained by fitting measured data for the three constituent binary systems are extrapolated to the ternary system using the method of Muggianu. Modeling results are compared to preliminary...

二组分合金相图是表示体系存在状态与组成、温度的关系，由于合金的沸点很高，所以合金相图一般是固-液相图。本实验研究的Bi-Sn合金相图是一种较为简单的合金相图，Bi和Sn这两种组分的液相完全互溶，固相部分互溶，故该体系的相图如图1所示 图1 Bi-Sn二组分合金相图示例 (来源：SGTE alloy database)本实验用步冷...

The thermodynamic properties and characteristic phase diagrams of some sections in the Ag–Bi–Sn system were calculated. The thermodynamic functions, such as Gibbs excess energy, activity and enthalpy of formation, were calculated using the RKM model and compared with experimental data reported in ...
Thermodynamic Analysis of the Sn-Ag-Bi Ternary Phase Diagram The present study was undertaken to examine the phase equilibria in the Sn-Ag-Bi ternary system, a promising candidate for use as a Pb-free solder. A regul... H Ohtani,I Satoh,M Miyashita,... - 《Materials Transactions》 被引...
Depending on temperature and concentration, the randomly distributed tin atoms order according to the BiF3 structure type. The results of this work have been implemented in a new version of the Cu–Sn phase diagram (Fig. 6). Download: Download full-size image Fig. 6. New Cu–Sn phase ...
