Abstract
Through the thermal mechanical simulation experiment，combined with the metallographic analysis and microhardness test on the Nb-Ti micro-alloyed steel for the austenitic continuous cooling process. The results shows that: with the increasing of the cooling rate, the phase transformation starting and ending temperature decrease and the ferrite content was decreased at room temperature. In less than 5℃/s low cooling speed region, with the increasing of the cooling rate, the grain size of tested steel obviously increases; In more than 17℃/s high cooling speed region, the grain size and vickers hardness of tested steel change and tends to be smoothly.
