在几种不同成分的微合金化钢中，对奥氏体静态再结晶动力学及其被应变诱导析出物暂时抑制的动力学进行了表征。这种抑制作用可以通过等温双变形试验获得的静态再结晶曲线中"平台"的形成来观察。研究了微合金化元素（Nb、V、Al）的种类和析出相的平均尺寸对再结晶抑制平台持续时间的影响，并得到了这些变量之间的经验关系。与Nb和V微合金化钢相比，Al钢具有更粗的粒度和更短的平台。
The kinetics of static recrystallization of austenite and its transitory inhibition by strain‐induced precipitates have been characterized in several microalloyed steels with different compositions. This inhibition can be seen by the formation of “plateaus” in the curves of static recrystallization obtained from isothermal double‐deformation tests. The influence of the type of microalloying element (Nb, V, Al) and the mean size of the precipitates on the duration time of the plateau of recrystallization inhibition has been studied and empirical relationships between these variables have been obtained. Al‐steels present a much coarser particle size and a considerably shorter plateau compared to Nb and V‐microalloyed steels.
