– distributions for (a) ferritic and (b) austenitic steel which correspond to an in-plane residual stress σ∥ = −1000 MPa and uniform strain-free lattice parameters a0. The gray areas mark the range of angles under which the strain-free lattice parameters are obtained for the biaxial stress state. The thickness of the anisotropic surface layer was assumed to be
