Summary

In the present study, the severe plastic deformation and the refinement accompanying it was effected by the two methods: high-pressure torsion (HPT) and equal channel angular extrusion (ECAP). The processed materials were examined in terms of microstructure heterogeneity on their mechanical properties. The aim was to find how various macro- and microscale parameters affect the mechanical properties of the material.
