摘要
回顾和分析了管线钢DWTT方法的建立过程、应用情况以及在高强度、高韧性、大壁厚管线钢中存在的DWTT异常断口问题。在综述目前该问题研究现状的基础上,通过研究和分析,提出了对DWTT异常断口的基本看法和处理方法。
The establishment and application of the DWTT method are reviewed. The abnormal fracture during DWTT of high strength, high toughess pipeline steel for thick wall pipes is also described. Based on the study the reason and countermeasures of abnormal fracture during DWTT are put forward.
