We experimentally investigated the rotation angle of the (220) plane in an aluminum single-slip system in which the angles of <110> and <111> in the single crystal were 45° relative to the tensile loading direction. Crystal rotation was investigated at several spots (50 × 50 μm) along <110> and <111> using synchrotron radiation white X-rays at the BL28B2 beamline of super photon ring-8. In measurements along the <110> axis, at an applied strain of ε = 5%, the relative crystal rotation of (220) in the vertical plane increased from 0.850° to 5.438° in the range of 0.9 to 1.4 mm. We observed the microstructure using a transmission electron microscope and verified the size of the dislocation cells or subgrains at each spot along <110>. The fundamental local crystallography revealed in this work should be helpful in establishing a method for evaluating ductile damage in materials.
