    The results of microstructure and phase composition investigations of titanium in different structural states (with average grain sizes of 0.3 μm, 1.5 μm, 17 μm, 38 μm) implanted by Al ions using the Raduga-5 and Mevva-V.RU sources are presented. The size, shape and localization of the formed phases (TiO2, Ti2O, TiC, Ti3Al, TiAl, Al 3Ti) depend strongly on the grain size of titanium target. In polycrystalline titanium after implantation by Al-ions the secondary phases (Ti3Al, TiAl, TiO2, TiC) formed in the body of grains of titanium matrix. It is shown that the nanostructural particles of TiO 2 phase are located mainly on dislocations in the body of target grains. An ordered Ti3Al phase is located at a depth of more than 200 nm in the implanted layer along the boundaries of the titanium grains. The TiAl3 phase formed on the grain boards in sybnano- and microstructural state of titanium targets. The improvement of the mechanical properties of titanium due to formation of the gradient structure of ion-alloyed surface layer was obtained.
