| 摘 要： | 对35CrMnS i钢电子束焊接进行了研究.结果表明,电子束焊接接头成形良好,无焊接缺陷产生.焊缝完全奥氏体化,在随后的快速冷却后形成以板条马氏体为主,并有少量残余奥氏体的组织.热影响区分为过热区、正火区和不完全淬火区,过热区为粗大马氏体组织,正火区为马氏体和贝氏体混合组织,而不完全淬火区为马氏体和铁素体混合组织.接头...

| Abstract: | The electron beam welding of(35CrMnSi steel) was studied.The results showed the appearance of electron beam welded joint was good,and no welding defects were found.The weld was fully austenitized,the rapidy solidified microstructure mainly consists of batten martensite while a small amount of residual austenite.The heat-affected zone can be divided into the overheated zone,normalized zone and slack quenching zone.The microstructure of overheated zone was coarse martensite.The microstructure of normalized zo... |
