Modeling of high-strength states in Al alloys

R.G. Chembarisova, I.V. Alexandrov


ne of the ways to improve the strength of metallic materials on the basis of Al alloys has been reviewed here. By the methods of mathematical modeling it has been shown that variability of the lattice misfit factor by matching the impurity atoms with the corresponding radii of atoms and their concentration in Al alloys, subjected to severe plastic deformation, can develop ultraifine grain structures, bringing to considerable strength increase.
