Abstract
The static and fatigue strength properties of commercially pure VT1-00 (Russian standart) titanium and the Zr-2.5 Nb zirconium alloy have been studied after equal-channel angular pressing (ECAP). It is shown that the formation of submicrocrystalline (SMC) structure upon ECAP leads to significant strengthening, increases the service life in a high stress amplitude range and increases the fatigue strength relative to those typical of the annealed state. The specific features of the fatigue fracture mechanism in different structural states of materials are studied.

Key words
titanium, Zr-2.5% Nb zirconium alloy, severe plastic deformation, submicrocrystalline structure, fatigue strength, propagation of fatigue cracks
