Laser Additive Manufacturing of Duplex Stainless Steel via Powder Mixture

Journal of Manufacturing and Materials Processing, 2022
Laser additively manufactured duplex stainless steels contain mostly ferrite in the as-built parts due to rapid solidification of the printed layers. To achieve duplex microstructures (ferrite and austenite in roughly equal proportions) and, thus, a good
