摘要
检测了X80管线钢不同轧制方向的力学性能,并分析不同位置的显微组织形貌和织构信息,讨论了显微组织和织构对管线钢力学性能各向异性的影响。X80管线钢板表面和中心面的织构有所不同,对力学性能各向异性影响较大的{001}<110>和{112}<110>织构占据主要地位:与轧制方向成0°方向的强度均高于45°和90°的,0°与45°方向的冲击性能接近,且均大于90°方向的。
The mechanical properties of the X80 pipeline-purposed steel in different rolling directions are tested,and the microstructure morphologies and the texture information at different positions are analyzed.And the effects of the microstructure and the texture on the anisotropy of mechanical properties of the X80 steel are also discussed.The textures of the surface and the central plane of the X80 steel plate are different,and the{001}<110>and{112}<110>textures that have significant effects on the anisotropy of mechanical properties occupy a dominant position.The strengths in the direction of 0°with the rolling direction are all higher than those in 45°and 90°directions,while the impacts in 0°direction and 45°direction are close to each other,and both are greater than that in the 90°direction.
