The austenite grain growth behavior and dynamic recrystallization behavior of low carbon Mn-Ⅴ steel were studied by Gleeble thermal simulation machine,TEM,SEM and quantitative analysis. The results show that the stable titanium carbonitride in steel containing titanium can prevent the effect of austenite grain growth during reheating process. Titanium added steel shows higher deformation resistance than titanium free steel,and its critical deformation for starting dynamical recrystallization is smaller than the latter. Compared with titanium free steel,titanium added steel is readily for recrystallization,and recrystallized grain growth speed is slower and resulted grain size is relatively finer.
