摘要:

对一种X100管线钢进行热模拟试验, 研究了过冷奥氏体的相变规律, 提出了一种得到以粒状贝氏体+板条贝氏体为主的混合组织的控轧控冷工艺制度, 分析了精轧变形量、冷却速度及终冷温度对实验钢微观组织的影响。结果表明, 随着变形量的增大实验钢的微观组织逐渐细化, 高强度的板条贝氏体含量减少而粒状贝氏体含量增多; 随着冷却速度的增加和终冷温度的降低实验钢组织中的板条贝氏体含量明显提高, 组织也逐渐细化; 组织中板条贝氏体含量较高时实验钢具有较高的强度, 但过多的板条贝氏体和针状M/A岛对材料的韧性造成不利的影响。

Abstract：

The transformation of undercooling austenite in a X100 pipeline steel was investigated by means of thermal simulation test. Based on the obtained results, a thermo-mechanical control process (TMCP) by which a mixed microstructure mainly consisted of granular bainite and lath bainite can be obtained has been proposed and effects of finish rolling deformation amount, cooling rate and final cooling temperature on microstructure have been analyzed. The results show that the microstructure of tested steel gradually refines and the volume fraction of lath bainite decreases with the increase of deformation amount. With the increase of cooling rate and the decrease of final cooling temperature, microstructure refines and volume fraction of lath bainite increases obviously. High volume fraction of lath bainite in microstructure is good for high strength. However, excessively high volume fraction of lath bainite and M/A islands with the shape of acicular have harmful influences on toughness.

Key words： metallic materials X100 pipeline steel deformation amount cooling rate final cooling temperature microstructure
