Continuous Cooling Transformation behavior of D460 Ship Plate Steel
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.
