概要
- 論文の詳細を見る
This investigation was undertaken to obtain a better understanding of the effect of nitrogen (N) on the solidification crack susceptibility of AISI (SUS) 304 austenitic-ferritic stainless steel weld metals, based on ductility curves at high temperatures, solidification process and microsegregation of phosphorus (P) and sulphur (S). It was confirmed that an increase in N had a detrimental effect on the cracking susceptibility of SUS 304 weld metals. This harmful effect of N was interpreted in terms of remarkable decreases in primary and residual δ-ferrite content and consequently an increased degree of microsegregation of P in particular.
