控轧含Nb钢板未再结晶温度T_(nr)的模拟计算

Calculation of Non-Recrystallization Temperature Tnrduring Controlled Rolling of Niobium Microalloed Steel Plates

通过考虑再结晶与析出之间的交互作用，计算了含Ｎｂ钢板在控制轧制过程中的未再结晶温度Ｔｎｒ，并分析了变形量和道次间隔时间对Ｔｎｒ的影响。Ｔｎｒ的计算值与双道次压缩实验中的实测值基本符合。

Nonrecrystallization temperature,Tnr,during the controlled rolling of niobium microalloyed steel plates has been calculated with the interaction between recrystallization and precipitation taken into consideration,and the effect of pass strain and interpass time on Tnr temperature is in a good agreement with the actual ualeres obtained from the two stage compression experiments
