用THERMECMASTOR Z试验装置及H 80 0型透射电子显微镜研究了一种Cr Mn Mo B钢热变形后中途改变冷却速度对贝氏体转变动力学的影响。试验结果表明 ,在连续冷却过程中 ,中途改变冷却速度将发生不同于连续冷却转变曲线所表示的转变特征
The influence of changing the cooling rate on the bainite transformation kinetics of a Cr Mn Mo B steel after thermal deformation was studied by THERMECMASTOR Z and H 80 0 transmission electron microscope. The experimental results show that during the continuous cooling process, changing the cooling rate in the midway will occur different from the transition characteristics indicated by the continuous cooling transition curve
