DEFORMATION FEATURES OF THE CENTRAL LAYERS OF Fe - 3%Si(110)[hkl] ALLOY BY ROLLING WITH A ROLL DIAMETER OF 90 MM

Abstract

The article presents the results of studies of the effect of initial crystallographic orientation and deformation modes on rolling texture in the central layer of Fe - 3%Si(l 10)[hkl]single crystals. Several groups of samples of single crystals were rolled under laboratory conditions. The groups of samples were classified according to the final deformation rate, the ideal crystallographic orientation of the rolling plane and deflections of the direction of the ideal orientation plane from the rolling direction. The methodology of the experiment took into account the amount of reduction rate during one rolling. Radiographic method was used to analyze the results of rolling. The obtained data was superimposed on a stereographic projection, and straight pole figures were built. The results of decoding direct pole figures revealed differences in the formation of the texture from the previously obtained results. The research shows the manifestation of the one-component deformation texture in the central layer.
