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.

Microhardness Distribution

The paper presents the results of the X-ray diffraction analysis of structural-phase states in the weld zone of a titanium alloy Grade2 in micro-and submicrocrystalline states. It is established that the structural-phase state in the weld zone and in the heat-affected zone depends on the state of samples of the alloy Grade2 before welding. It is shown that formation process of metastable phases ω-Ti and α′′-Ti occurs in the submicrocrystalline state in the alloy Grade2 in the weld zone and in the heat-affected zone. Investigations of the features of the microhardness distribution in the weld zone in alloys Grade2 in micro-and submicrocrystalline states are carried out. Different character of microhardness distributions in the weld zone in the samples depending on the structural-phase state of welded plates made of alloy Grade2 is determined.
