The formation of texture and microstructure in polycrystalline Cu and Cu-5 wt. % Al alloy during two modes of homogenous rolling have been compared. Two samples of each metal were rolled. One sample was rolled unidirectionally, while the other by reverse rolling. Some differences in the textures depending on the rolling mode have been observed in the range of deformation of the Cu-5 wt. % Al alloy where intensive twinning took place. It was also found that the texture of reverse rolling was more homogeneous across the thickness of the rolled alloy sheet than the texture of unidirectionally rolled material. No clear effect of the rolling mode on microstructure has been observed.

The subject of investigation is the ridging phenomenon occuring in ferritic stainless chromium steels. The origin of this undesirable surface phenomenon is connected with the observed strips of texture inhomogeneities showing plastic anisotropy. Basing on measurements of crystallographic orientation topography the texture inhomogeneities together with the ridging effects have been investigated in sheets from earlier stages of the production process. The proposed changes in the traditional technological processing of sheets obtained from this steel type are intended to limit the occurrence of the ridging effect.
