Abstract
The layer-by-layer structural and texture ingomogeneities of hot-rolled 55KhN2MA-Sh steel sheets are studied by X-ray diffraction. Hot rolling of the steel forms a substantial layer-by-layer texture inhomogeneity in the sheets: the {112}\(\left\langle {111} \right\rangle \) and {110}\(\left\langle {112} \right\rangle \) texture components prevail in the external layers in the sheets; the {100}\(\left\langle {110} \right\rangle \), {112}\(\left\langle {110} \right\rangle \), and {554}\(\left\langle {225} \right\rangle \) texture components prevail in the central layers; and texture is very weak in the intermediate layers. The crystallographic texture is shown to influence the anisotropy of the mechanical properties of the sheet. The layers with different crystallographic textures are found to exhibit different mechanical properties and different anisotropy coefficients. The anisotropy of the properties is characteristic of the central layers, and it is less pronounced in the external layers of the hot-rolled sheets.
