摘要
文章对11.00 mm厚度规格的L360M管线钢卷板进行了夏比摆锤冲击试验和落锤撕裂试验。试验结果表明,同板幅相应位置的韧性差异较小。从DWTT试验试样断口的宏观形貌可以看出,试样挠度越大,锤断后断面呈现的试样扭曲越明显,甚至会有个别试样因为翘曲导致无法彻底锤断。
In the paper,it is introduced the Charpy pendulum impact test and drop weight tear test(DWTT)of L360M pipeline steel coil plate with the thickness specification of 11.00 mm.The test results showed that the differences of toughness at relevant positions of the same plate are smaller.It can be seen from the macroscopic morphology of fracture of samples for DWTT that the bigger the deflection of samples,the more obvious the distortion of samples for fracture after hammering to breakage,even some samples could not be hammered to breakage completely because of warping.
