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%).

An experimental study by the “method of grids” of the deformations’ degree and nature in the longitudinal and transverse sections of the pipe walls with their bending and rolling for different diameters and materials was carried out. The obtained results allow to calculate these deformations, to estimate the nature of the distribution of residual stresses and to predict the magnitude of the pipe walls’ thinning and the overall service life.
