After rotary forging at 700°°C, the alloy manifests the best combination of the structural, mechanical, and functional characteristics. In this state, the long-length bar stock demonstrates a homogeneous grain structure with a certain fraction of a dynamically polygonized substructure of β-phase, a satisfactory strength (UTS=580 MPa), a low Young’s modulus (E=35 GPa), high difference between dislocation and phase yield strength (Δσ = 280 MPa), and a relatively large amount of superelastic recovery strain (εrSEmax=3.12%).
