Abstract: The fatigue failure of titanium with submicrocrystalline (SMC) and microcrystalline (MC) structure formed during severe plastic deformation after exposure to high hydrostatic pressure was investigated. The features of the pressure effect on the conditional fatigue limit for SMC and MC titanium were identified and analyzed.

Keywords: ВТ1-0, submicrocrystalline titanium, ultrafine-grained structure, fatigue, internal stresses, nanopores.
