Role of shielding gas in tailoring microstructure and anisotropy in wire arc additive manufactured Inconel 686

Abstract This study examines the effect of shielding gas composition on the microstructure and mechanical properties of Inconel 686 components fabricated via wire arc additive manufacturing (WAAM). Thin-walled structures were produced using pure Argon (Ar), a 50% Helium-Argon mixture (Ar + 50% He),...
