Figure 6
Principle of the modified multi-wavelength method. The different pictograms in this and all following figures are intended to indicate that the actual DEC models (i.e. directional in the surface layer, isotropic in volume) are used for data generation, while the volume model is assumed for data analysis (i.e. stress evaluation). The simulated sin2ψ curves in (a) refer to the case of an austenitic steel and a diffraction angle 2θ = 16°. (b) and (c) Depth profiles obtained for the in-plane stress and the strain-free lattice parameter, respectively. For the surface layer a thickness z* = 10 µm was assumed. See text for further details.
