Abstract

The influence of mechanical-pulse treatment (MPT) on diffusion (mass transfer) of alloying elements in surface layers of titanium alloys has been investigated. The studied materials were pure titanium VT1-0 (α-structure) and titanium alloy VT6 (α+β-structure). The MPT was carried out in special environments for carburizing and for nitriding. The results of investigations show that concentration of nitrogen and carbon in surface layers after MPT is higher in comparison to the virgin materials. The mechanism of diffusion of alloying elements from the technological environment to surface layers under conditions of high speed thermoplastic deformation is discussed. This fast diffusion leads to changes in structure and phase compositions of the treated surface layers and improvement of their physical and mechanical properties.
