FIELD: nonferrous metallurgy.
SUBSTANCE: invention provides axially unsymmetrical pieces with thickness less than 10 mm and made from β-titanium or quasi-β-titanium alloy. Microstructure of the core is formed by whole grains having degree of extension above 4 and equivalent diameter 10 to 300 μm. Manufacturing method envisages providing emailed blanc, converting it, if necessary, into elongated piece, forging elongated piece, hardening forged elongated piece, and annealing hardened forged elongated piece. Such piece can, for example, be a blade for turbine compressors. Optimal geometry enables improvement of aerodynamic properties and thereby working characteristics of engine, wherein the piece is utilized.
EFFECT: improved performance characteristics and prolonged service time.
