摘要
高温高压相图在物理化学、矿物学、地球科学和极端条件下的材料科学中都具有重要的地位和应用价值,相图计算方法(alculation of phase diagram,CALPHAD)是建立温度-压强热力学相图和热力学数据库的主要方法,可以计算材料体系的相平衡、组成相的相分数和相成分、热力学性质,一定程度上解决单一实验建立高温高压相图的困难。本文对基于CALPHAD的高温高压相图建模方法进行了详细介绍,并总结其当前面临的问题和下一步研究方向,为极端条件下材料设计和性能评估奠定基础。
High temperature and high pressure phase diagrams have a very important position and application value in physical chemistry,mineralogy,earth science and material science under extreme conditions.Calculation of phase diagram(CALPHAD)method is the main method to establish temperature-pressure thermodynamic phase diagram and thermodynamic database,which can calculate the phase balance of the material system,the phase fraction and phase composition of the component phase and thermodynamic properties,to a certain extent solving the difficulty of establishing a high temperature and high pressure phase diagram in a single experiment.This paper introduces the current high temperature and high pressure phase diagram modelling method based on CALPHAD in detail,and summarizes the current problems and future research directions,laying a foundation for material design and performance evaluation under extreme conditions.
