摘　　要：通过双道次压缩试验,研究了高强低合金钢Q390在奥氏体区的软化行为,分析了变形温度与间隔时间对静态软化行为的影响,采用应力补偿法计算了静态再结晶百分数,确定了Q390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 hot deformed austenite of HSLA Q390 was studied by double-pass compression method,and the influence of temperature and interval time was analyzed.The softening percentage of static recrystallization was defined by the 0.2% stress offset method.The static recrystallization activation energy of Q390 was determined and the static recrystallization kinetics model to predict the evolution of softening was devoleped.

关 键 词：Q390 静态再结晶 激活能 动力学模型
