X-ray peak broadening analysis of AA 6061100 − x − x wt.% Al2O3 nanocomposite prepared by mechanical alloying

► Integral breadth methods using various Williamson-Hall models were investigated for line profile analysis. ► Uniform energy density deformation model is observed to the best realistic model. ► The present analysis is used for understanding the stress and the strain present in the nanocomposites.
