The effect of alloying with vanadium and nitrided vanadium on the structure of the functional layer of a forming roll from cast iron is studied. The influence of the content of the introduced alloying addition on variation of qualitative and quantitative parameters of the components of the microstructure is determined. The changes in the sizes, the graphite and carbide contents, and the content of retained austenite is investigated. The most expedient content of the introduced vanadium and nitrided vanadium for minimizing the content of retained austenite in the microstructure of the cast iron is determined.
