Abstract

A thermodynamic description of the Al-Cd-Mg ternary system has been developed using the CALPHAD (CALculation of PHAse Diagrams) approach, based on critical assessment of the three constituent binary systems: Al-Cd, Al-Mg, and Cd-Mg, and considering available experimental data and information on phase equilibria, crystallography, and constitutional information from literature. The solution phases, liquid, Hcp_A3 and Fcc_A1, are modeled using the Redlich-Kister formalism. Ternary solubilities of the binary phases Al₃Mg₂, Al₁₂Mg₁₇, Al₃₀Mg₂₃ and of the binary ordered phases, Cd₃Mg, CdMg and CdMg₃, are included. Comparisons between calculated results and experimental data for the liquidus projection and two isothermal sections demonstrate good agreement, confirming that the proposed thermodynamic model reliably reproduces the phase equilibria of the Al-Cd-Mg system. A consistent set of thermodynamic parameters has thus been obtained for application in computation assisted Al-Cd-Mg alloy design.

铝-镉-镁体系热力学描述

基于对三种二元体系：Al-Cd、Al-Mg和Cd-Mg的关键评估，并考虑到有关相平衡、晶体学和文献中的构成信息的现有实验数据和信息，使用CALPHAD（相图计算）方法开发了Al-Cd- mg三元体系的热力学描述。液相Hcp_A3和Fcc_A1采用Redlich-Kister形式建模。包括二元相Al3Mg2、Al12Mg17、Al30Mg23和二元有序相Cd3Mg、CdMg和CdMg3的三元溶解度。液相线投影和两个等温剖面的计算结果与实验数据吻合良好，证实了所建立的热力学模型可靠地再现了Al-Cd-Mg体系的相平衡。从而获得了一组一致的热力学参数，可用于计算辅助的Al-Cd-Mg合金设计。

期刊介绍： The design of industrial processes requires reliable thermodynamic data. CALPHAD (Computer Coupling of Phase Diagrams and Thermochemistry) aims to promote computational thermodynamics through development of models to represent thermodynamic properties for various phases which permit prediction of properties of multicomponent systems from those of binary and ternary subsystems, critical assessment of data and their incorporation into self-consistent databases, development of software to optimize and derive thermodynamic parameters and the development and use of databanks for calculations to improve understanding of various industrial and technological processes. This work is disseminated through the CALPHAD journal and its annual conference.
