abstract = {In order to enable and promote the adoption of novel
material processing technologies, a comprehensive
understanding of the residual stresses present in structural
components isrequired. The intrinsically high energy input
and complex thermal cycle during arc-based additive
manufacturing typically translate into non-negligible
residual stresses. This studyfocuses on the quantitative
evaluation of residual stresses in an Al–6Cu–Mn alloy
fabricated by wire and arc-directed energy deposition. Thin,
single-track aluminum specimens that differ in their
respective height are investigated by means of
energy-dispersive high-energy X-ray diffraction. The aim is
to assess the build-up of stresses upon consecutive layer
deposition. Stresses are evaluated along the specimen build
direction as well as with respect to the lateral position
within the component. The residual stress evolution suggests
that the most critical region of the specimen is close to
the substrate, where high tensile stresses close to the
material’s yield strength prevail. The presence of these
stresses is due to the most pronounced thermal gradients and
mechanical constraints in this region.},
