Residual stress and texture control in Ti-6Al-4V wire + arc additively manufactured intersections by stress relief and rolling [PDF]

, 2018
Additively manufactured intersections have the theoretical risk to contain hydrostatic tensile residual stresses, which eventually cannot be thermally stress relieved.

Measurement and Modelling of Residual Stress in Wire-Feed Additively Manufactured Titanium [PDF]

, 2018
Residual stresses were characterised in a wire-feed additively manufactured titanium alloy component. A numerical simulation based on the inherent strain method was used to model residual stresses arising from the manufacturing process.

Wire arc additive manufacturing of porous metal using welding pore defects

Materials & Design, 2023
A novel wire arc additive manufacturing process is proposed to produce porous metal (PM). The innovation is to convert harmful welding pore defects into a beneficial structure of PM, and then the PM parts can be additive manufactured layer by layer.
