- 論文の詳細を見る
Knife line attack occurring in welded joints of stabilized austenitic stainless steels is a serious problem because of fatal failure of the constructions being caused at an early stage of use. In this report, the mechanism of this phenomenon was discussed based on the electron microscopic observations and quantitative considerations about the behaviours of carbides in HAZ. Effect of rare earth metals (REM) addition on knife line attack sensitivity was also investigated. As the result, it was made clear that the sensitivities of SUS 321 and SUS 347 were considerably improved by the addition of REM.
