摘要: 本工作通过CALPHAD方法获得Al-Si-Mg-Ce相图热力学数据库。通过比较Al-7Si-0.6Mg-0.4Ce关键四元合金的Scheil凝固模拟和实验测定的相变温度与凝固微观组织，验证了所建立的热力学数据库的可靠性。结果表明，热力学计算和实验结果的高度吻合，证明了建立的Al-Si-Mg-Ce热力学数据库的可靠性，为Al-Si-Mg材料设计提供一种策略。
Abstract: In this work, a thermodynamic database for the Al-Si-Mg-Ce system was established via the CALPHAD approach. The reliability of the developed database was validated by comparing the Scheil solidification simulation of the key quaternary alloy Al-7Si-0.6Mg-0.4Ce with experimentally determined phase transformation temperatures and solidification microstructure. Results demonstrate a high consistency between thermodynamic calculations and experimental data, confirming the reliability of the constructed Al-Si-Mg-Ce thermodynamic database and providing a strategic pathway for the design of Al-Si-Mg-based materials.
