Figure 1
Optimization procedure for refining the residual stress depth profile and the grain interaction model in the near-surface region of an austenitic stainless steel of type TP347H (ASTM A213), which is commercially applied for superheaters in thermal power plants. Example taken from Genzel et al. (2023BB15). (a) Minimization of the total path length between the individual stress values shown in diagram (b). The diagrams (c) [stress depth profile determined for the Eshelby–Kröner (K) grain interaction model] and (d) [depth profile obtained for the optimized (O) grain interaction model] represent section enlargements of the area closest to the surface. See text for further details.
