INFLUENCE OF HOT-REDUCTION PARAMETERS ON THE STEEL AUSTENITE STRUCTURE OF A RAILWAY WHEEL

Abstract

The formation of grain structures with boundaries similar to substructures is one of the factors contributing to grain refinement in hot-reduction carbon steel. At the forming of a rim, the slight cooling-down (100-150°С) of the surface volumes is sufficient to increase their strength characteristics. After that, an increase in the magnitude of the hot-hardening of metal in the central rim volumes will lead to the formation of a more uniform fine-grain austenite structure over the rim section.
