A method for refining the profile of quasibreathers in the space of all initial atoms displacements is developed in the framework of the density functional theory. The method is exemplified by the procedure of constructing the discrete breathers in graphane.

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.
