摘要：
The Al-Sr system is thermodynamically assessed by means of the CALPHAD (CALculation of PHAse Diagrams) method. Three stoichiometric compounds, Sr8Al7, SrAl2, and SrAl4, are included in the modeling. The terminal solid solutions, (bSr), (aSr), and (Al), are described to show negligible solubilities. A Redlich-Kister formula is used to describe the liquid phase. A set of consistent thermodynamic parameters is obtained by considering reliable experimental data. The calculated phase diagram and thermodynamic properties agree reasonably with the corresponding experimental data. (C) 2003 Elsevier B.V. All rights reserved.
