Dynamic theory of possible morphological characteristics of austenite nanocrystals formed upon the α–ε–γ transformation in Fe–Ni alloys via deformation and shuffling of {110}α planes

Abstract

In dynamic theory, one of the possible variants of the formation of martensite crystals upon the reverse α–γ transformation in Fe–Ni alloys connected with the participation of the intermediate e phase is discussed. The mechanism of planar tension–compression deformation of {110}<inf>α</inf> planes is considered. A set of characteristic morphological features for crystals of the γ phase has been found, which indicates the participation of the ε phase in their formation and includes the material orientation relationships close to the ideal Kurdjumov–Sachs orientation relationships. © 2015, Pleiades Publishing, Ltd.
