We have shown that hybrid manufacturing has the potential to fabricate 316LSS parts with superior strength than the wrought materials and with a ductility higher than additive manufacturing and comparable to wrought materials. In this presentation, the effect of texture and residual stresses on the mechanical performance of 316L stainless steel fabricated by additive and hybrid manufacturing will be comparatively investigated using advanced characterization techniques and strain hardening analysis. The effect of residual stresses and texture on twin generation in the as-fabricated component and the effect of twins in the as-fabricated component on the deformation mechanism will be discussed. Using the results, the higher strength and elongation of hybrid manufactured 316L components will be rationalized.
