Résumé

This paper presents the conception, design and manufacturing of a new equipment for nanostructuring the metals – aluminium alloy in the present case- by multidirectional shearing process. Changing the path of the deformation lead to an accumulative strain that cause the shear of the grains. By controlling the path of the deformation with the possibility to change the direction of the deformation, the accumulated strain increases up to 60% so that the that the grain size produced are almost 100 nm. The equipment that allows implementation of the proposed method is presented with details concerning functioning and possibilities to be industrial scale implemented.
