摘要：

The present paper deals with investigations of fatigue and tensile mechanical properties of ultrafine-grained commercial pure (CP) titanium where different nanostructures were processed by various regimes of severe plastic deformation. It has been established that ultimate strength, yield stress and fatigue strength both for low-cycle and high-cycle region of all ultrafine-grained samples were essentially higher than those of the traditional coarse-grained titanium. The highest level of properties was revealed in CP Ti having nanostructure which contented ultrafine grains of 0.2 mum with internal substructure.
