Abstract
Development of inhomogeneous plastic strain in three-dimension had been measured in cold rolled aluminium-magnesium alloys that contain small lead particles, which are marker of local strain measurement, by using synchrotron radiation microtomography. Local inhomogeneous deformation during thermo-mechanical processing is very important for controlling mechanical properties of metallic materials, for example strength and formability, because localized deformation would affect not only formation of deformation microstructure but also development of recrystallized microstructure. The strain distributions in different magnesium content were compared with texture development investigated by SEM/EBSD. The mechanism of texture development affected by local deformation is reported.
