Two different analytical models are derived for the estimation of the temperature drop in the two deformation stages of radial-axial ring rolling process of flat rings. The temperature estimation, along with previous results regarding geometry, strain and strain rate, is used to calculate the variation of the flow stress of the material during the process and accordingly to derive the process forces, utilizing different forces estimation models already available in the literature.

Abstract
Two different analytical models are derived for the estimation of the temperature drop in the two deformation stages of radial-axial ring rolling process of flat rings. The temperature estimation, along with previous results regarding geometry, strain and strain rate, is used to calculate the variation of the flow stress of the material during the process and accordingly to derive the process forces, utilizing different forces estimation models already available in the literature.
