摘要
在备有拉伸装置的 S—550型扫描电镜上对粒状贝氏体组织的微观变形及断裂过程进行了原位观察,讨论了影响粒状贝氏体组织中各相变形的有关因素。
The dynamic microprocesses of fracture in granular bainite were observedby the in-situ technique in SEM equipped with tensile platform.The expression about thepartition of strain in dual phase structures was derived.The affecting factors on ductility indual phase structures were also discussed.
