许多管线钢的机械性能随试样相对于钢板轧制方向和横向的取向而变化。这种各向异性限制了钢的最佳设计和开发，并且其发生归因于诸如断裂期间的显微组织条带和相关分层以及不利取向的铁素体解理面等效应。通常很难将这些因素分开，但已经设计并实施了一个实验来研究晶体织构的作用。结果表明，织构在影响夏比试验能量的各向异性方面起着重要作用。(c)2012爱思唯尔有限公司版权所有。
Many linepipe steels exhibit a variation in mechanical properties as a function of the orientation of the test sample relative to the rolling and transverse directions of the steel plate. Such anisotropy limits the optimum design and exploitation of the steel, and its occurrence has been attributed to effects such as microstructural banding and the associated delamination during fracture, and unfavourably oriented ferrite cleavage planes. It is often difficult to separate the factors, but an experiment has been designed and implemented to study the role of crystallographic texture in isolation. It is demonstrated that the texture plays a major role in influencing the anisotropy of the Charpy test energy. (c) 2012 Elsevier B.V. All rights reserved.
