The experiments of a micro-alloyed high strength steel under different strain, strain rates, deformation passes and cooling rates were conducted on the thermal-simulator of THERMECMASTOR-Z.The effects of deformation parameters on microstructure and phase transformation of the micro-alloyed high strength steel were analyzed.It has been found that the Ar3 temperature decreases with the increase of the cooling rate.The higher the strain rate, the higher phase transformation temperature.Phase transformation temperature increases with the increase of strain.The ferrite grain will be refined and the pearlite amount will be decreased by the increase of strain, using multi-pass deformation and high cooling rate.The temperature range of dual-phase region (γ+α) is more than 140 ℃.
