abstract = {Additive manufacturing (AM) of parts is typically
associated with the generation of high residual stresses
because of repeatedexposure to high thermal gradients.
Non-destructivemeans of mapping the residual stresses are
required for optimising theseprocesses and/or mitigating
such stresses by thermal treatments. However, the reliable
determination of residual stress in AMparts remains
challenging. Here, neutron diffraction, as well as
energy-andangle-dispersivesynchrotron X-raydiffraction
havebeen used to map the residual stress within a laser
powder bed fusion (LPBF) additively manufactured stainless
steel 316L arch.The arch was designed by the
EASI-STRESSproject as a residual stress benchmarking
exercise in order to compare differentresidual stress
analysis techniques. Residual stresses were determined along
two scan lines deep within the bulk of the component. The
results for the different neutron and synchrotron
instruments are found to broadly agree with a standard
deviation of 50 MPa or better, as well as with those
predicted by an inherent strain finite element model. The
results show near-yield level residual stresses and suggest
that both synchrotron X-ray diffraction and neutron
diffraction can be used to reliably determine the residual
stress in LBPF parts.},
