In this work we present the results of investigations of ultrafine-grained iron obtained as a result of multicycle extrusion through a bent channel with 90 degrees centigrade bending angle. Strained samples were subjected to annealing. The investigations were focused on material structure characterization (TEM) and determination of its hardness (HV0.2).
