Abstract
Nanocrystalline and submicrocrystalline titanium are synthesized using the methods of severe plastic deformation by twisting and equal channel angular pressing with subsequent cold rolling. The microhardness, magnetic susceptibility, and electrical resistivity have maximum values in highly strained titanium. Annealing in the temperature range of 673–1123 K leads to restoration and recrystallization manifested in decreases in the microhardness by a factor of 2, in the magnetic susceptibility by 15%, and in the resistivity by 20%.
