Abstract Scope |
Recently, research efforts of novel steel alloys, where high strength and toughness are critical features, have significantly expanded. A proven method to achieve high performance is via the Hall-Petch effect. While the additive manufacturing (AM) directed energy deposition (DED) technology provides a novel and effective way for producing significant grain refinement (by imposing a rapid cooling rate upon solidification), its inherent complexity merits a need for the development of a systematic DED framework that quickly identifies the ideal printability space for a given steel, and subsequently enables one to print the material to full density and dimensional accuracy. Afterwards, achieving optimal strengthening in novel high strength steels via DED and the Hall-Petch effect would be much more straightforward. To meet this need, the present study proposes a DED printability framework using 316L stainless steel, following an approach that is easily adaptable to other high-end steel alloys. |
