Abstract

We present the results of in-situ studies of evolution of grain boundary misorientations in ultrafine grained (UFG) aluminum alloy Al-4%Cu-0.5%Zr during annealing. It was found that relaxation processes during annealing are accompanied by grain rotation.We present the results of in-situ studies of evolution of grain boundary misorientations in ultrafine grained (UFG) aluminum alloy Al-4%Cu-0.5%Zr during annealing. The structure of the UFG alloy was obtained by severe plastic deformation method. Misorientations between the grains were measured using single reflection technique. It was found that relaxation processes during annealing are accompanied by grain rotation. Analysis of the kinetics of grain rotation in the discrete-dislocation approach has demonstrated a good agreement between the numerical estimates and the experimental data.
