<p>The deformation of steel 20 under stepwise uniaxial cyclic tensile loading with different stress ratios (R &gt; 0) was experimentally investigated. Cyclic tests of five-fold cylindrical specimens cut from the material of pipe elements were carried out on the INSTRON electrohydromechanical installation. The test program consisted of three modes of asymmetric loading with stress control. Each mode was implemented in the form of a stepwise cyclic loading with a variable value of a certain cycle parameter: amplitude stress at a constant value of the mean, mean at a constant value of the amplitude, and both amplitude and mean at a constant value of the maximum cyclic stress. The loading level corresponded to the low-cycle fatigue region with significant elastic-plastic deformation of the material. A comparative analysis of the obtained uniaxial ratcheting (cyclic creep) diagrams of steel 20 under stepwise cyclic tensile loading was performed with ratcheting diagrams under similar stepwise biaxial loading of pipe elements made of the same steel by cyclic internal pressure. It is shown that the deformation process of the specimens under stepwise loading is similar to the deformation of pipe elements. However, the values of ratcheting deformations of the specimens are 1.5 to 2 times higher than the ratcheting deformations of pipe elements under similar loading programs, which can be explained by their greater stiffness under biaxial loading by internal pressure and the absence of a yield point in the first half cycle. The accumulation of ratcheting deformations of the specimens in the first section of unsteady cyclic creep is monotonic, in contrast to the deformation of tubular elements. Comparison of the kinetics of irreversible deformation accumulation under different loading programs indicates the greatest influence of amplitude cyclic stresses on the ratcheting process compared to average or maximum cyclic stresses.</p>
