以规则溶液亚点阵模型和经典型核长大理论为基础，计算了Nb-Ti-V复合微合金化钢的应变诱导析出动力学．计算所得的析出-时间-温度（PTT）曲线与采用等温应力松弛法所获得的实验结果基本符合。
The strain-induced precipitation kinetics of Nb-Ti-V composite microalloyed steels was calculated based on the regular solution sub-lattice model and the classical theory of core growth. The calculated precipitation-time-temperature (PTT) curve is in good agreement with the experimental results obtained by the isothermal stress relaxation method.
