Results are provided for experimental studies of complex loading for steels 45 and 40Kh along trajectories of constant curvature κ1 in plane 1 -∋ 3 of the Ilyushin deviator space of strains. Strain curves for the materials and loading trajectories corresponding to the strain trajectories realized are plotted. It is shown that the strengthening of steel 40Kh in deformation along a closed curvilinear trajectory of constant curvature may be very marked (up to 70% or more) in contrast to steel 45 whose strengthening does not exceed 10%, and stress-strain state parameters are stabilized even in the second loop of the trajectory.
