摘要：
The formation process as well as the orientation distribution of subgrains were monitored during cyclic equal channel angular (ECA) pressing. Pure Al with 99.9% purity was used. The ingot was prepared my melting Al pellets and casting into a rectangular mold. Pure Al after cyclic pressings was analyzed using TEM. The sample had a deformation structure comprised of submicron grain that are elongated in the direction of shear.
