Vt20 Titanium Alloy

The article presents the results of studies of titanium alloy VT20 in ultrafine-grained (UFG), subfine-grained (SMG), fine-grained (MZ) and mesopolycrystalline (MPC) states, obtained, including by methods of plastic deformation and subsequently subjected to ion implantation. The effect of grain size on the structural-phase state of the titanium alloy surface and mechanical properties is shown.

Results of surface modification of the VT-23 titanium alloy by high flux of copper ions with an energy of 2 keV and ion current density of 3.5 mA/cm2 was studied. The dependence of the microhardness and penetration depth of ion as function of duration of ion treatment was determined. Structural-phase state of ion-modified of the VT-23 titanium samples surface layer was investigated by TEM and SEM. Microhardness was researched by nanoindentation method.

Abstract The paper presents the experimental results of studies of the temperature dependence of inelastic and plastic strains during torsion of coarse-grained samples of the Ti49.3Ni50.7 (at.%) alloy. Investigations of the deformation behavior of the test alloy samples in the martensitic, two-phase and high-temperature states have been carried out. It is shown that the value of the summary inelastic strain reaches a maximum value of ∼ 18% under deformation of the samples in the martensitic and two-phase state, as well as in the temperature range of pre-transition phenomena.
