Crack mitigation at interface between Inconel 718 and stainless steel 316L during directed energy deposition under N2 atmosphere

The objective of this study is to elucidate the mechanisms by which nitrogen (N2) shielding gas mitigates the cracking phenomenon at the interfaces between Inconel 718 (IN718) and stainless steel 316L (316L) during directed energy deposition (DED). When these two alloys were joined under an argon (A...
