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

Ferrite content measurement in super duplex stainless steel welds [PDF]

Welding in the World, 2018
Approaches to determining ferrite fraction (%) and ferrite number (FN) were examined for super duplex stainless steel (SDSS) welds. A reference sample was produced by bead-on-plate gas–tungsten arc welding of a type-2507 SDSS plate. By comparing different etchants and measurement practices, it was realized that etching with modified Beraha followed by ...
