Nanoindentation and glancing angle x-ray diffraction were performed on samples of hot rolled aluminum alloy 5xxx in order to characterize the mechanical properties of its Near Surface Micro-structures (NSMs). Nanoindentations with a sharp indenter were carried out up to maximum depth of 5000 nm close to the near surface.The indentation parameter studied here is the hardness given that the residual strain fields are correlated with the hardness value. Glancing angle diffraction is performed with incident angle up to 1 degree. The plastic deformation and strain percent were found using Williamson-Hall plots. The reported results provide evidence for the ability to use glancing angle x-ray diffraction as a tool for the measurement of plastic deformation as a function of depth in the material.
