摘　　要：基于热模拟双道次压缩实验研究了高铌HTP合金钢奥氏体区变形后道次间隔时间内的软化行为,分析了变形温度与间隔时间对静态软化行为的影响,得出了实验钢的静态再结晶激活能,并建立了静态再结晶动力学模型。The softening behavior of deformed austenite of Nb-microalloyed steel within interval of passes was studied using double-pass compression method, and the influence of temperature and interval time was analyzed. The static recrystallization activation energy of tested steel was determined and the static recrystallization dynamics model could be described.
