Processes of formation of structure and properties in the functional layer from chromium-nickel cast iron of two-layer centrifugally cast indefinite forming rolls under crystallization and subsequent tempering are investigated. The temperatures of the start and finish of the phase transformations, the phase composition, and the contents of martensite and retained austenite in the material of the functional layer after the tempering are determined.
