| Abstract Scope |
While the additive manufacturing (AM) directed energy deposition (DED) technology provides a novel and efficient method for printing high strength steels to novel geometries, 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 martensitic steels via DED and the Hall-Petch effect would be much more straightforward. To address this need, the present study develops a DED printability framework, where an advanced high strength martensitic steel known as AF9628 is printed to full density, high strength, and respectable ductility (ρ > 99%, UTS > 1.2 GPa, εf > 10%). The introduced process optimization framework is easily adaptable to other high-end steels and alloys and should prove quite valuable to the AM research community. |
