The paper presents results of studying the deformation of Grade 5 alloy samples while they are heated to temperatures ranging between 900 and 1350 K at constant tensile stresses of 4.45; 6.91 and 9.36 MPa in air and argon environments.The processing of the results has allowed us to evaluate the empirical coefficients for the Grade 5 alloy in two dependences obtained earlier for the Ti-5Al and Grade 2 alloys. One dependence relates creep rate to heating temperature, tensile stress, and creep activation energy; the other one relates creep deformation onset temperature (residual creep deformation within 1 hour of holding is 0.2%) to the conventional short-term creep limit.
