Near-surface RS in LPBF IN718 for as-built samples with different scanning strategies
Laser Powder Bed Fusion (LPBF) is and Additive Manufacturing (AM) method which allows the fabrication of complex structures that cannot otherwise be produced via conventional subtractive manufacturing methods. A large body of research has been dedicated in recent years to the optimization of LPBF process parameters. This proposal is part of an internally funded project at the Bundesanstalt für Material Forschung- und prüfung (BAM) that focuses on the influence of scanning strategies on the formation of residual stresses (RS) in an LPBF IN718 alloy. Due to the interaction of temperature gradients and build geometry, the RS fields can have complex variations from the surface to the bulk. The proposers have published a range of work on LPBF IN718 material, combining microstructural characterisation, energy dispersive synchrotron diffraction for subsurface RS and neutron for bulk stresses. In the literature, the near-surface RS are often blamed for the failure of components. Therefore, there is interest to determine the possibility of subsurface maxima not captured by the near-surface measurement techniques.
