Fundamental achievements of the dynamic theory of reconstructive martensitic transformations

Abstract

Basic directions in the theory of martensitic transformations are specified. Instances of solving several important problems in the context of dynamic theory of reconstructive martensitic transformations are reviewed. An fcc-bcc (bct) transformation in iron alloys is referred to as example. Much attention is given to certain concept-affiliated aspects. In particular, the key role of the concept of initial exited state in conceiving transformations with crystal growth at supersonic speed is shown. An additional emphasis is made at showing that this concept is of primary importance in both calculating critical rates of austenite cooling and evaluating the scale of incubation-period-related times at bainitic transformation. © (2013) Trans Tech Publications, Switzerland.
