摘要
利用热力学数据库和相图计算进行材料成分设计,可以有效减少实验时间,缩短开发周期,为新型铜铬系合金提供理论指导。使用动力学数据库模拟材料在热处理过程中的第二相尺寸、元素浓度以及析出相等相关信息,能够为热处理工艺制定提供计算指导。介绍了CALPHAD方法发展历程及研究方法,综述了基于CALPHAD方法对电工合金微结构设计及制备工艺优化的研究进展,并指出了应用发展方向。
Using thermodynamic database and phase map calculation to design material composition can effectively reduce the experimental time,shorten the development cycle and provide theoretical guidance for the new copper-chromium alloy.The use of dynamic database simulation materials in the heat treatment process of the second phase size,element concentration and precipitation of equal information,can provide computational guidance for the heat treatment process.This paper introduces the development course and research method of CALPHAD method,summarizes the research progress of the design and preparation process optimization of electro-alloy microstructure based on CALPHAD method,and puts forward the application direction.
