Abstract

In this study, the origin of separations is investigated in modern high strength pipeline steels. In-depth microstructure characterization and property correlation is used to demonstrate that preferred crystallographic planes are responsible for the generation of separations in thermomechanical rolled steels with high cleanliness. Further insights on the influence of crystallographic orientation are obtained by performing different types of standard and non-standard tests with specific specimen and notch orientations and evaluating the related crack propagation path. Finally, special texture components are identified, which determine whether in-plane fracture, splitting or deflection of the cleavage parts take place. This study assists in understanding the separation phenomenon in modern high strength pipeline steels across the different test methods. Furthermore, it amplifies that the separations in thermomechanical rolled steels with high steel cleanliness are inherently linked to the orientation of specific crystallographic planes and are not necessarily an indication of a poor material behavior.

热轧管线钢力学试验中发生分离的意义
本文研究了现代高强度管线钢中分离的原因。深入的微观结构表征和性能对比表明,在高清洁度的热机械轧钢中,优选的晶体平面是产生分离的原因。通过使用特定的试样和缺口取向进行不同类型的标准和非标准测试,并评估相关的裂纹扩展路径,进一步了解了晶体取向的影响。最后,识别特殊织构成分,确定解理部分是否发生面内断裂、劈裂或挠曲。本研究有助于理解现代高强度管线钢在不同试验方法下的分离现象。此外,它放大了具有高钢材清洁度的热机械轧钢中的分离与特定晶体平面的取向内在地联系在一起,而不一定是不良材料行为的指示。
