The presence of heterogeneous deformation is a one of key issue in a prediction model of deformation texture development. Recently, not only local strain mapping but also crystallographic orientation mapping is possible to obtain within aluminum alloy by using synchrotron radiation. In this study, local strain mapping and orientation mapping were obtained by microtomography and three-dimensional X-ray diffraction using synchrotron radiation in Al–4Pb alloy. Simulation of deformation texture evolution has been performed based on crystal plasticity model. The simulation started from actual microstructure and the obtained local strain was applied. The simulation produced similar microstructure to the actual one. Therefore, heterogeneous strain distribution is very important for the development of deformation texture.
