摘　　要：研究变形温度和变形量对微合金元素碳氮化物在形变奥氏体中析出的影响,观察了不同变形工艺下奥氏体中析出物形貌。研究表明:变形量越大,变形温度越低,实验钢奥氏体中析出物数量越多,析出物平均尺寸越小。This paper studies the effect of deformation temperature and deformation amount on the precipitation of carbonitride in the austenite of low carbon bainitic steel and describes the morphologies of precipitation phase under different deformation processing. The results showed that the more the deformation amount was, the lower the deformation temperature. In addition, the more the amount of precipitation in the aus tenite was, the smaller the average size.
