<p>Adoption of pulsed laser irradiation during laser-based directed energy deposition (DED-LB) resulted in substantial microstructural modifications of super duplex stainless steel, leading to significant enhancements in mechanical and corrosion properties after solution annealing. Inherent coarse and columnar grain structure, typical of conventional DED-LB, was inhibited by pulsed high-energy laser input and a refined solidification microstructure was developed. Low-speed high-frequency deposition by the pulsed process promoted strong &lt; 001 &gt; _bcc epitaxy of ferrite toward laser paths, rather than vertical building direction, and induced pronounced texture components in both phases. The modified grain morphology and associated crystallographic orientations were largely retained after the annealing operation, demonstrating a strong microstructural and texture memory from as-built condition. The alloy developed by pulsed DED-LB exhibited enhanced mechanical performance, particularly in terms of ductility and toughness, compared to its conventionally processed counterpart. Elemental analysis and quantitative measurements revealed significantly fewer and smaller Mn- and Si-enriched oxide inclusions in the specimen produced by pulsed laser process, which contributed to reduced pit initiation tendency under corrosive environment. The grain-refined specimen exhibited more noble open-circuit potential and reduced corrosion rate. However, its repassivation was slightly delayed, likely due to lower atomic density of crystallographic planes ({001}_bcc, {101}_fcc, and {001}_fcc) exposed at the test surface during potentiodynamic polarization. This highlights a trade-off between enhanced general corrosion resistance and localized film recovery. The results underscore a complex interplay between microstructure, inclusions, and passivity.</p>
