中文摘要：
根据降水并且就降水行为和化学作文(Si 和 Mn ) 上的紧张的效果而言的热力学的计算，从奥氏体的降水的动力学为不同温度和紧张被调查了。成核理论和在奥氏体的铌，碳，和氮的溶度积被用来作为温度和作文的功能在降水的开始时间导出方程。在 Avrami 方程的 n 的值从出版报告用可得到的试验性的数据被决定，它显示 n 是温度的一个经常的独立人士，降水的结束时间是 n 的一个函数和降水的开始时间。开始时间的价值和新模型预言的降水的结束时间与试验性的价值相比，一个好协议在两个之间被获得。
英文摘要：
On the basis of the thermodynamic calculation of precipitation and considering the effect of strain on the precipitation behavior and chemical composition （Si and Mn）, the kinetics of precipitation from austenite has been investigated for different temperatures and strains. Nucleation theory and the solubility product of niobium, carbon, and nitrogen in austenite have been used to derive equations for the start time of precipitation as a function of temperature and composition. The value of n in Avrami equation was determined using the available experimental data from the published reports, which indicated that n is a constant independent of temperature and the end time of precipitation is a function of n and the start time of precipitation. The values of the start time and end time of precipitation predicted by the new model are compared with the experimental values and a good agreement was obtained between both.
