The austenite dynamic recrystallizing process of VIF melted and forged 625 mm bar of Nb-V-Ti microalloying 0. 37C-1.45Mn non-quenched and tempered steel (/%: 0. 37C
0. 60Si
1. 45Mn
0. 025Nb
0. 078V
0.017Ti) with single pass compression
strain rate 0. 1 ~ 10 s
-1
and reduction by 60% at 950 ~ 1 150 ℃ has been studied by using Gleeble-3800 thermal simulation machine. Results show that of Nb-V-Ti microalloying 0. 37C-1. 45Mn steel the higher deformation steel and the lower strain rate
the smaller deformation cumulative energy to occur the dynamic recrystallization and the more easily to carry out the dynamic crystallization. Due to containing Nb in steel
the activation energy of dynamic recrystallization of test steel is higher
