Mechanical and functional properties of Ti48.6Ni49.6Co1.8 shape memory alloy rods with diameters of 3.5 and 4.5 mm were studied after rotary forging (RF). The structure was analyzed using optical microscopy. Mechanical properties were determined by uniaxial tensile and Rockwell hardness tests. Temperature range of martensitic transformations was defined by differential scanning calorimetry. Superelasticity effect was studied by a thermomechanical method using bending tests. The obtained results showed that RF at 450 °C and RF + annealing at 450 °C, 1 hour allow manufacturing 3 m-long Ti-Ni-Co rods with diameters of 3.5 and 4.5 mm with improved mechanical properties: (RF: σB = 1180 MPa, σ0.2 = 625 MPa, δ = 15 % and σB = 1205 MPa, σ0.2 = 622, δ = 16 %, respectively; RF+ annealing: σB = 1292 MPa, σ0.2 = 651, δ = 19 % and σB = 1228 MPa, σ0.2 = 575 MPa, δ = 21 %, respectively). The temperature range of superelastic behavior was determined as ‒30 to 20 °C with the value of completely maximum superelastic strain – 5.0 %.
