摘　　要：对实验室试制的X80级高级别管线钢力学性能进行研究,利用Gleeble-1500热模拟试验机对高级别管线钢的动态再结晶模型进行研究。结果表明:此次实验室试制的厚度为11 mm的X80高级别管线钢力学性能优良,屈服强度645MPa、抗拉强度735MPa、屈强较低(0.88),在-20℃条件下,实验钢的冲击功平均值为280J。The influence factor and recrystallization behavior of high grade pipeline steel was investigated by Gleeble-1500 thermal simulation machine. The results indicate that the steel shows excellent mechanical properties, with an average yield strength of 645MPa and an average tensile strength of 735MPa. The average impact energy of the steel is 280J at-20℃.
