| 摘 要： | 利用Calphad技术和应用Pandat相图计算软件,重新评估了Al-Si-Fe体系液相投影图,550、727、800℃等温截面,以及不同成分合金在1 477℃时的液相混合焓。结果表明,计算所得相图及液相混合焓与实验数据相符,该工作建立的热力学模型及参数可作为外推建立Al-Zn-Si-Fe等高元体系数据库的基础,并对相关体系的材料设计工作具有重要的指导意义。 |

| Abstract: | Thermodynamic optimization of the Al-Si-Fe system was performed by Calphad method considering the experimental phase diagrams and thermodynamic properties data available from literature.The liquidus surface of Al-Si-Fe system,isothermal sections at 550,727,800 ℃ and the heat of mixing of liquid alloys at 1 477 ℃ was re-evaluated.The calculated thermodynamic properties as well as phase diagrams for the ternary systems agreed well `with the experimental data. |
| Keywords: | Al-Si-Fe Ternary System Phase Diagram Thermodynamic Calculation |
