利用平衡态分析方法，研究了析出物形成元素含量波动对Ｔｉ－ＩＦ钢高温固溶规律的影响，发现了一些新现象，为今后生产中控制第二相粒子形成元素的固溶含量提供理论参考。 The equilibrium state analysis method was used to study the influence of the content of precipitates on the solution of Ti-IF steels at high temperature. Some new phenomena were found, which provided a theoretical reference for the control of the solid solution content of the second phase particles in the production in the future .
