静态再结晶在设计微合金化钢的可控轧制工艺规程中起着重要作用。这种软化机制对奥氏体钢的热强度和热轧钢的最终显微组织有显著的影响,因而对热轧钢的最终性能也有明显的影响。诸如Nb、Ti、B等添加元素都会在时间上延迟静态再结晶。人们广泛承认,奥氏体再结晶的推迟,部分是由溶质原子的拖曳作用造成的,而且也会由应变诱发沉淀而引起,后者的作用通常更强。
Static recrystallization plays an important role in the design of controllable rolling schedule for microalloyed steels. This softening mechanism has a significant effect on the hot strength of the austenitic steel and on the final microstructure of the hot-rolled steel, which also has a significant effect on the final properties of the hot-rolled steel. Additional elements such as Nb, Ti, B, etc., delay the static recrystallization in time. It is widely acknowledged that the postponement of recrystallization of austenite is partly caused by the dragging of solute atoms and also by strain-induced precipitation, the latter being generally more potent.
