The phase composition, structural state and mechanical properties of the ion-alloyed surface layers of titanium implanted by the Al ions have been investigated. Ion implantation of the Al ions into titanium was carried out using the plasma-flow, vacuum-arc ion source "Raduga-5". It was found out that increase of the dose of Al ions from 2.2·1017 ion/cm2 to 2.2·1018 ion/cm2 led to the increase of the ion-alloyed layers thickness from 400 nm to 2600 nm. It was established that the fine dispersed equilibrium intermetallic phases Ti3Al, TiAl and the solid solution of aluminium in titanium were formed in the ion-modified layers. The increased average size of the intermetallic particles took place with the irradiation dose increasing. The agglomeration of the nanoscale particles occurred above the dose 6.2·1017 ion/cm2. It was found out, that the mechanical properties of the implanted Ti were higher than of the unimplanted material.
