Abstract

The article examines industrially applicable manufacturing processes for high-pressure compressor blades made of titanium alloys – specifically those with the most widely used dimensions and a «dovetail» root design. The article presents the results of experimental studies on the microstructure and mechanical properties of starting materials – bars and forgings (both individual and group forgings) made from heat-resistant titanium alloys VT41 and VT46, produced via various manufacturing routes. The study demonstrates the feasibility of achieving high mechanical properties and technical-economic indicators for the manufacture of high-pressure compressor blades from VT41 and VT46 alloys using group blanks.
