摘要(Abstract)：

利用热模拟、力学性能测试和材料显微分析等实验技术,研究了X80管线钢在延迟加速冷却条件下的组织与性能的变化。结果表明,通过延迟加速冷却,X80管线钢可获得贝氏体+铁素体(B+F)双相组织。随着始冷温度的上升,试验钢的B含量增加,F含量降低,导致材料屈服强度上升,塑性下降。当始冷温度为530℃时,X80管线钢有较低的屈强比,较大的均匀伸长率和较大的形变强化指数,符合大变形管线钢的技术要求。通过延迟加速冷却方法获得的细小的B板条和较高位错密度的F赋予材料较高的强韧特性和优良的大变形能力。

关键词(KeyWords)： X80管线钢;延迟加速冷却;始冷温度;组织和性能
