摘　　要：研究结果表明 :该钢在 950℃以下变形时 ,由于动态析出的作用 ,很难发生动态再结晶 ;在变形后的等温过程中 ,950℃以上 ,则易进行再结晶 ,而在 750℃时 ,等温 30min无静态再结晶发生。The studied results showed that it was difficult to dynamic\|recrystallize as the hot deformation was below 950℃, because of dynamic precipitation. In isothermal process after hot deformation, it was easy to recrystallize as the temperature was high 950 ℃, and the recrystallization didn't occurred as isothermal time was 30min at 750 ℃.
