A modified EN AW 3003 aluminium alloy prepared by twin-roll casting method was processed by constrained groove pressing (CGP) at room temperature. The influence of number of CGP passes on the final microstructure was studied by means of electron and light optical microscopy. Inhomogeneous distribution of grain orientations and size evoked by CGP was observed. Microhardness mapping has proven that such an inhomogeneity is always linked to an inhomogeneous distribution of microhardness along the strip cross-section.
