Abstract

Hot rolled and annealed at 320 °С AZ31 sheets are featured by low anisotropy of strength (~3 %), significant anisotropy of yield stress (~15 %) and specific elongation (~12 %). Monocrystal adjectives of mechanical properties and the values of those properties in different directions in the plane of sheets, and in the direction perpendicular to the sheet planes after deformation by different number of cycles of sign-variable bending were calculated on the data of mechanical properties measuring in the plane of sheets and the results of Х-ray texture analysis in the model of orthorhombic quasimonocrystal.
