本文研究了铬镍奥氏体焊缝中铝对铁素体含量和形态的影响及其与焊缝韧性的关系。得出了铁素体形态与焊缝韧性之间的联系;并首次提出了研制渗铝钢焊条时,设计焊缝成分的公式。
In this paper, the effect of aluminum on the ferrite content and morphology in the chrome-nickel austenitic weld and its relationship with the toughness of the weld were investigated. The relationship between the morphology of ferrite and the toughness of the weld was obtained. The formula for designing the weld composition was also proposed for the first time when the aluminized steel electrode was developed.
