Abstract
Martensitic hardenable (maraging) stainless steels are of interest due to their combination of high strength and ductility along with superior corrosion and stress corrosion cracking properties. Corrax maraging steel has been recently atomized in powder form for laser-based sintering applications . In the current study, Corrax with a nominal composition of 11–13% Cr, 8.4–10% Ni, 1.1–1.7% Mo, 1.2–2% Al and 0.05% C (in wt%) was additively manufactured through direct metal laser sintering (DMLS) process. This additive manufacturing technique results in ultrafine microstructures with unique micron and submicron characteristics. The microstructure of the as-built DMLS -Corrax was investigated using SEM, EBSD , and TEM . The result of the current study is the preliminary step to develop additively manufactured high strength Corrax stainless steels for various applications .
