Conclusions

  1. 1.

    Heat treatment, which includes the decomposition of supercooled austenite in the region of the diffusion transformation with the attainment of highly disperse pearlite, is recommended for the realization of a favorable combination of reslience and endurance limit in carbon steel. In this case, segregations of structurally free ferrite are eliminated to the maximum degree.

  2. 2.

    The differential cooling of the elements of a wheel during its hardening makes it possible to regulate the stress distribution across the wheel's section with allowance for the effect of thermal braking loads.
