Microstructure and texture of magnesium alloy AZ31 sheets subjected to accumulative roll bonding (ARB) were studied after 1 and 2 passes through the rolling mill. Sheets after the ARB process exhibited a very fine grain structure and significant basal texture. Tensile experiments were performed at room temperature. Distinctive planar anisotropy of mechanical properties was estimated. This anisotropy is explained by the slip crystallography and twinning.
