Abstract: The paper investigates an innovative technological processing method for fabricating nanostructured materials for structural applications. Severe plastic deformation (SPD) and subsequent thermomechanical treatment, was used to produce high physical and mechanical properties in bulk billets.

Abstract: This paper studies the effect of combined SPD treatment on microstructure and mechanical properties of semi-products out of CP Ti. The combined processing, consisting of equal-channel angular pressing and further thermomechanical treatment, produced ultrafine-grained rods out of Grade 2 CP Ti with a diameter of 6.5 mm and a length of up to 1 m. It was established that the formation of homogeneous ultrafine-grained structure in Ti rod with α-grain size of about 100 nm allowed to enhance yield stress by 200% in comparison with initial annealed state.
