A comparative study of additive manufacturing techniques: Residual stress and microstructural analysis of CLAD and WAAM printed Ti–6Al–4V components (2016, unknown): “Additive manufacturers [13,5,14,15] have been trying to eliminate these problems by extensive study of AM process parameters targeting simultaneously the economical and environmental benefits of additive over conventional manufacturing.”
Residual stress and texture control in Ti-6Al-4V wire + arc additively manufactured intersections by stress relief and rolling (2018, background): “The reason is the absence of lateral restraint, resulting in lateral deformation rather than longitudinal straining, which would eliminate the residual stresses [2]–[4].”

Interpass rolling of Ti-6Al-4V wire + arc additively manufactured features for microstructural refinement (2018, unknown): “Interpass rolling has predominantly been applied to thin (< 10mm) walls and the rollers often have a similar profile to the deposit [7,12] (Fig.”
