Abstract. The aim of this contribution was to compare four methods of residual stresses determination of single-phase and dual-phase steels after cold-rolling primarily using X-ray diffraction techniques. Firstly, without taking into account the preferred orientation (sin2ψ method), secondly from the geometry of four-point bending, thirdly without neglecting the texture (harmonic function method). And mainly, the new method, by calculating anisotropic elastic constants as a weighted average between single-crystal and X-ray elastic constants with weighting being done according to the relative intensities in the measured directions. The applicability of the new method of residual stresses determination in textured materials was proofed; however, the method needs further verification.
