Aluminum and silicon influence on gas saturation of titanium alloys
Oles Honchar Dnipro National University, 72 Nauky Ave, 49045 Dnipro, Ukraine
The article dials with current issues of refining titanium alloys by electron beam melting (EBM) to reduce gas saturation, which is important for improving their technological and operational characteristics. Correlations between the content of aluminium, silicon and mechanical properties of titanium alloys have been identified, which allows optimizing their composition to increase the tensile strength. It has been established that the interaction of titanium with gases, with oxygen, significantly affects the formation of the surface layer, oxide films and changes in the mechanical characteristics of alloys. An analysis of changes in the surface microhardness of titanium alloys VT1-0 and VT6S at different temperatures has been carried out. The phase composition of the surface layer after heat treatment was studied by X-ray diffraction, which confirmed the formation of oxides and intermetallic, such as TiO2, Ti3Al and Ti3O5. The results obtained contribute to further improvement of titanium alloy processing technologies and development of materials with improved characteristics for use in aircraft production and materials science.
