Impact of the phase composition and structural state on the corrosion and mechanical strength of titanium alloys of the pseudo-β class

摘要

Analysis of the phase composition, microstructure, and mechanical properties of the semifinished materials made of the pseudo-β alloy of VT22 grade after strengthening thermal treatment in different modes was carried out. Evaluation of the corrosion and mechanical strength of the semifinished materials made of the VT22 alloy was performed. Recommendations on selection of the strengthening thermal treatment mode providing the optimum set of properties were given.
