摘要
文章利用Gleeble-1500热模拟试验机研究了SUPER82B硬线钢在温度为900℃-1050℃、变形速率为0.10s^-1-10s^-1条件下的热变形行为。通过奥氏体再结晶动力学回归计算了SUPER82B硬线钢的动态再结晶激活能、峰值应力σm与变形温度、应变速率之间的关系,动态再结晶临界应变εc和动态再结晶完成应变εs与ln（Z）的计算模型,给出了反映该钢动态再结晶进行过程的动态再结晶状态图等,为合理预报和控制SUPER82B硬线钢的组织和性能提供基本依据。
The hot deformation behavior of SUPER82B hard wire steel was studied with a compression test by using Gleeble-1500 simulator at the temperature of 950℃-1050℃ and strain rate of 0.10s^-1-10s^-1.The deformation activation energy,the relationship between the peak stress σm with the deformed temperature and strain rate,the critical strain εc and the steady strain εs with the ln（Z） were calculated.The dynamic recrystallization（DRX） state were analyzed to access the DRX progress with different hot-working condition.The aim of this experiment is to provide basic data of the prediction and control for the microstructure and properties of SUPER82B products.
