Bazyl' O. Effect of ion and electron irradiation on crystal structure and properties of Ti-V-Al alloy

The object of study: Alloy of Ti-V-Al. The aim of study: to find of general regulars of structure and surface morphology, element and phase compositions changes after low energy high current electron beam (HCEB) irradiation, single and double implantation, complex treatment (i.g. after double implantation of cupper and nickel ions and subsequent electron beam irradiation) for controlling of physical and mechanical properties of titanium alloys. Methods and equipment: Rutherford backscattering spectroscopy, nuclear elastic resonance analysis, X-ray diffraction, transmission, scanning and atomic force microscopes, wear resistance, microhardness and fatigue starch tests, coefficient of friction measurement. Theoretical and practical results, newness: The firstly, the complexinvestagation of structure, element and phase compositions of Ti-V-Al alloy after cupper and nickel ion implantation and subsequent HCEB effect has been done/ It has been shown, that consecution and implantation dose an influences on c oncentration of implanted elements. The calculation of thickness of layer, melted after single and double cupper and nickel ions implantation into. Three compound Ti-V-Al alloy hat Iowa 25 and 47 nm accordingly. The firstly, the following regulars have been found: the electrons beam irradiation of implanted samples result in second phase with legal elements forming, if its concentration above 1 at.% and its not form row unbreak off of solutions with titan. It has been found that double implantation and complex treatments result in improvement of follow characteristics of titanium alloy: microhardness, coefficient of friction, wear resistance and fatigue strange. The sphere of application: mechanical engineering, physic of metals.
