在Ｇｌｅｅｂｌｅ ２０００热模拟实验机上通过变形同时水淬和减少变形量的方法，对普通低碳钢低温变形获得超细晶铁素体的机制进行了研究．结果表明：超细晶铁素体的获得主要是形变诱导铁素体和铁素体动态再结晶两种机制共同作用的结果在８７Ｏ－７６０℃低温８０％变形可以获得的等轴均匀超细品铁素体．形变量控制铁素体的析出量和动态再结晶．应变速率影响形变诱导铁素体所需的临界变形量．冷却过程对铁素体的析出量不产生决定性影响，但可以控制晶粒长大速度。
On the Gleeble 2000 thermal simulation machine, the mechanism of obtaining ultrafine-grained ferrite by low temperature deformation of ordinary mild steel was studied by means of deformation, simultaneous water quenching and reduction of deformation. The results show that the ultrafine-grained ferrite is mainly obtained by the combination of the two mechanisms of deformation-induced ferrite and ferrite dynamic recrystallization. The equiaxed uniform ultrafine product Ferrite. Deformation control of ferrite precipitation and dynamic recrystallization. Strain rate affects the amount of critical deformation required for deformation-induced ferrite. The cooling process does not have a decisive influence on the amount of ferrite precipitated, but can control the grain growth rate.
