Abstract
The structural evolution during high-temperature deformation of chromi um-manganese high-nitrogen austenitic steel stable to gamma --> alpha transformation has been studied. High mobility of twin boundaries is r evealed. The transformation of network-type misoriented structure to f ragmented structure is estimated quantitatively and the possible mecha nisms of this transformation are shown. The boundary migration and the fragmentation at the boundaries are associated with the preliminary t ransition of boundary fragments to excited high-energy state.
