【摘要】 使用Fact Sage商业软件重新评估Fe-O-U三元体系。在考虑了已发表文献中的固液相变温度、不变平衡温度和热力学性质数据之后,得到了一组自洽的Fe-O-U三元体系热力学参数。本评估覆盖了体系中的所有成分和温度范围。计算所得相图和热力学性质与可信赖的试验数据较好吻合。更多还原

【Abstract】 This thermodynamic description of Fe-O-U ternary system was reassessed with the commercial software Fact Sage. After considering literature data of solidus-liquidus temperatures,invariant equilibrium temperatures and thermodynamic properties, a group of self-consistent thermodynamic parameters of Fe-O-U ternary system was developed. Estimation covers all the composition and temperature range in the system. The calculated phase diagrams and thermodynamic properties meet well with all the reliable experiment information.更多还原
