摘　　要：采用热膨胀法获取X100管线钢的CCT曲线,并通过硬度实验,光学显微组织观察,SEM组织观察,TEM组织观察等手段进行分析,深入讨论了X100管线钢的CCT曲线及其在不同冷却条件下的相变规律,研究了X100管线钢不同冷却条件下的组织类型及典型特征,为更好的认识X100管线钢组织-性能之间的关系和推动其工业应用提供重要参考。CCT curve of the X100 pipeline steels was established by thermodilatometric analysis method,and then it was analysed through hardness test,OEM,SEM and TEM observing.The CCT curve and the rule of phase transformation at different cooling conditions were investigated profoundly,and the structure style and its typical characters of the X100 pineline steels was discussed which tremendously helped understanding the relationship of the structure and performance and provided an important reference for the industry applications.
