摘　　要：利用平衡态分析对Ｔｉ－ＩＦ钢析出物形成元素含量波动对高温二相粒子的析出规律进行了研究，得到了析出物开始析出时各个析出物形成元素含量的临界值，对ＭｎＳ析出条件有了新的认识，并给出了Ｍｎ加入后所造成的各析出物元素重组关系示意图。ln present paper, by means of equilibrium analysis, the effects of con- tent of all the precipitates on the equilibrium precipitation behavior of Ti - IF steel were studied. The critical value of each precipitate's composition element at which begins to precipitate was caculated. Furthermore, the conditions of MnS precipitating were clari- fied. At mean time a molecular structure rebuilding mechanism schematic diagram of all precipitate compostition element was shown when MnS existed.
