abstract = {The resistance to service loads and defects of additively
manufactured structures can be significantly reduced due to
residual stresses induced by inhomogeneous cooling during
the manufacturing process. For duplex stainless steels
solution annealing at approx. 1050°C is the only
industrially accepted stress relieve treatment. This is
often accompanied by severe deformation due to the low creep
resistance of the alloy at this temperature. For economic
reasons the parts should be used in the as-built state,
where the residual stress distribution needs to be
considered. We determined the residual stress distribution
of simplified pressure vessel geometries using high energy
white beam X-ray radiation and the hole drilling method. As
a result of this study, two building strategies were
evaluated for their ability to produce a compressive
residual stress state on the media facing side of the
parts.},
