| Popis: | We show that energy-dispersive X-ray diffraction is a very powerful tool for the investigation of complex stress fields which occur in the surface region of polycrystalline materials after plastic deformation. The interplanar spacings of 11 lattice planes of a ground steel plate were investigated for ψ angles up to 88°, covering a penetration depth of the X-rays from 0.04 to 60 μm. The results were evaluated according to a novel formalism and yield the variation in the residual stress components σ 11 ( z ) and σ 22 ( z ) with the depth z below ground surface. The formalism and the results are critically discussed. |
