X65 pipeline steel is mainly used in the manufacture of oil and gas pipelines, requiring high strength, high toughness, brittle fracture and good welding performance, but it is easy to appear slab defects in the continuous casting process, which will reduce the comprehensive performance of pipeline steel. In the paper, the high-temperature plasticity of X65 pipeline steel slab is studied. The hot tensile test is carried out by using Gleeble-1500D thermal simulation testing machine, and under the strain rate of 2.0 × 10-3/s, deformation temperature of 700~1 300 ℃, the fracture strength and the section shrinkage change with temperature are analyzed. The fracture morphology is observed by scanning electron microscope, and the cause of fracture is clarified to provide a theoretical basis for continuous casting production.

X65管线钢主要用于加工制造油气管线,要求其具有高强度、高韧性、抗脆断以及良好的焊接性能,但在连铸过程中易出现铸坯缺陷,会使管线钢的综合性能降低。文章针对X65管线钢铸坯进行高温塑性研究,利用Gleeble-1500D热模拟试验机对其进行热拉伸实验,分析应变速率为2.0 × 10-3/s变形温度700~1 300 ℃变形条件下的断裂强度和断面收缩率随温度的变化情况。通过扫描电镜对断口形貌进行观察,明确了断裂原因,为连铸生产提供理论依据。

X65管线钢主要用于加工制造油气管线,要求其具有高强度、高韧性、抗脆断以及良好的焊接性能,但在连铸过程中易出现铸坯缺陷,会使管线钢的综合性能降低。文章针对X65管线钢铸坯进行高温塑性研究,利用Gleeble-1500D热模拟试验机对其进行热拉伸实验,分析应变速率为2.0 × 10-3/s变形温度700~1 300 ℃变形条件下的断裂强度和断面收缩率随温度的变化情况。通过扫描电镜对断口形貌进行观察,明确了断裂原因,为连铸生产提供理论依据。

X65 pipeline steel is mainly used in the manufacture of oil and gas pipelines, requiring high strength, high toughness, brittle fracture and good welding performance, but it is easy to appear slab defects in the continuous casting process, which will reduce the comprehensive performance of pipeline steel. In the paper, the high-temperature plasticity of X65 pipeline steel slab is studied. The hot tensile test is carried out by using Gleeble-1500D thermal simulation testing machine, and under the strain rate of 2.0 × 10-3/s, deformation temperature of 700~1 300 ℃, the fracture strength and the section shrinkage change with temperature are analyzed. The fracture morphology is observed by scanning electron microscope, and the cause of fracture is clarified to provide a theoretical basis for continuous casting production.
