In this study, plane strain compression has been applied to aluminum alloy with dispersed Pb particles for local strain measurement. The 3D local plastic strains of individual grains were investigated using synchrotron radiation tomography (CT) by tracking the marker Pb particles. Crystallographic orientations in the inside of grains were also measured on the polished cross-section of the strain-measured sample by means of EBSD. The relationship between local plastic strain and local misorientation within grain was investigated on individual grain with considering orientation components of typical rolling texture. It is suggested that the experiment can discover mechanisms of microstructural evolution induced by plastic deformation in polycrystalline metals, although clear relationship between them could not be definitely clarified in this research due to only one condition of the plane strain compression.
