Abstract

It is shown that deformation mode at more intensive reductions on blooming mill raises compactness of dendritic structure, promotes the formation of required homogeneous and fine grain structure of normalized railway axles and reduces number of additional heat treatments.

Keywords: RAILWAY AXLE, DEFORMATION, NORMALIZATION, MICROSTRUCTURE
