本文研究35MnVN锻造用非调质钢高温形变再结晶行为,以及形变工艺对金相组织的影响.试验结果表明,35MnVN钢发生再结晶的临界形变量较大,形变温度,形变量对再结晶数量影响较小,形变温度>1100℃发生动再结晶,形变温度<950℃不发生再结晶,形变温度在1000～1050℃间为静再结晶区,易产生混晶组织.不同形变工艺下,金相组织中的铁素体、珠光体及贝氏体的形态及数量不同。
In this paper, 35MnVN forging non-quenched and tempered steel high temperature deformation recrystallization behavior, as well as the deformation process on the microstructure.The results show that 35MnVN steel recrystallization of the critical deformation is larger, deformation temperature, deformation of recrystallization quantity The deformation is less than 950 ℃, the recrystallization is not affected and the deformation temperature is between 1000 and 1050 ℃ in the zone of recrystallization, and the mixed crystal structure is easy to produce.During the different deformation process, Phase organizations in the ferrite, pearlite and bainite morphology and the number of different.
