Hardening features for high manganese steel cores of crosspieces along the way

摘要

Herein are established main regularities of steel hardening and defect formation for the working conditions of cross-pieces along the way in order to be able to further reduce the number of samples without losing informativity about the metal functioning of cross-piece. The change in the hardness of the metal along the depth of the cross section at the stage of steady wear occurs with the wear rate of the cross-piece. From the surface of the cross into the depths of the cross section, the hardness of the metal decreases. The rule of change can be considered linear. The generalized results of studies of susceptibility of cross-pieces metal for defects showed that the processes of contact defect occurrence and their expansion on the cross-pieces are fatigue-like.
