摘要
对离心球铁管开裂承口断口的显微形貌及形成原因进行了研究。开裂承口存在一种细片状组织,对解理断裂的产生有一定的影响,而元素偏聚至晶界是沿晶断裂的主要原因。
In this paper, the morphology of the fracture surface has been studied by SEM and analysed for its forming' The cleavage fracture is mainly due to the existence of fine lamellate structure.The intergranular rupture is due to the elements segregation towards the grain boundary.
