The structure of VT1-0 samples was studied after fatigue tests under cyclic loading in sub- and microcrystalline states after additional treatment with high hydrostatic pressure. Fractographic studies of fatigue fracture surfaces have been performed using optical and scanning electron microscopy. Using the method of backscattered electron diffraction and transmission electron microscopy on thin foils, the evolution of the grain and dislocation structure, as well as the crystallographic texture of the studied material, has been studied. The parameters of the defective structure (nanopores) were determined using small-angle X-ray scattering and densitometry. The differences in the fracture patterns of the sub- and microcrystalline states of titanium VT1-0 under different fatigue loading parameters are discussed. Keywords: titanium, VT1-0, microstructure, fracture, nanopores, fatigue.
