Role of Special Boundaries in Structural and Phase Transformations in Metals and Alloys. 1. Deformation and Recrystallization

Abstract

The works of the Department of Heat Treatment and Metal Physics of the Ural Federal University performed for over 20 years with the aim to study the laws of the evolution of special misorientations — boundaries (SMB) in metallic materials under deformation, recrystallization and phase transformations are reviewed. The first part of the review is devoted to the concept of the principal role of SMB in the changes of texture under structural transformations in metals and alloys, where they are treated as carrier “genes” of the structure and texture heredity. The second part of the review will present the results of generalization of the concept to processes of texture variation under phase transformations.
