摘要(Abstract)：

为给403Nb马氏体热强钢热连轧组织性能预报积累数据,用Gleeble-3500热模拟试验机对403Nb进行了双道次热压缩试验。热压缩试验进行的温度为950～1150℃,应变速率为0.01～10s-1,道次间隔时间(ISDT)为1～300s。研究了变形参数,如温度,应变速率和道次间隔时间对静态再结晶和组织的影响,结果表明:第一道次的峰值应力随应变速率的增加而增加,但第二道次的峰值应力随着变形温度的降低和道次间隔时间的缩短而增加;当变形温度一定时,应变速率的增加可以提高静态再结晶率;静态再结晶率随着道次间隔时间的增加先增后降。403Nb在道次间隔时间为100s时,静态再结晶率最高。
