Abstract
The studies are represented of phase and structure transformations during the process of multi-stage heat treatment of large-scale rolls. Adapted analytical models are introduced and applied to the calculation of phase transformations together with the finiteelement models of rolls. The results show phase components distribution over the hardened layer of rolls of the special alloy steels 50CrMnMoV and 45Cr3MnNiMoV at different stages of the manufacturing process.
