Abstract

The paper presents comparison of main mechanical properties of rods, forgings and castings made of heat-resistant titanium pseudo-alpha alloy VT46 (VT46L), as well as similar alloys of the same class and application in the range of operating temperatures. Values of long-term strength at 500 and 550 °С have been presented specifically. The article shows microstructure study results of the said semi-finished products material. It provides a generalized description of the technology for manufacturing semi-finished products, indicating features that distinguish VT46 alloy from serial titanium alloys. Possible application areas of VT46 alloy in relation to engine parts and aircraft equipment are discussed.
