The Nature, Mechanism and Properties of Strong Bainite
: Consistent with the wishes of the Conference Organisers, the basic theory of the bainite reaction including the crystallographic, thermodynamic and kinetic framework is described, together with the development of fine bainite and its properties.
متن کاملKinetics of the bainite transformation
A theory is developed for the evolution of bainite as a function of time, temperature, chemical composition and austenite grain size. The model takes into account the details of the mechanism of transformation, including the fact that nucleation begins at the austenite grain surfaces, and that the growth of a sheaf occurs by the repeated nucleation of small platelets. Predictions made using the...
متن کاملThe Bainite Controversy
There has long existed a controversy regarding the formation of the bainite phase in steels. Nonetheless, following the clear identification of bainite in 1930, several characteristic features associated with the bainite transformation became well established. These features include: the classification into upper and lower bainite; the existence of a bainite-start temperature; and the incomplet...
متن کاملPOSCO Lectures: The Bainite Reaction
Examination of a time–temperature–transformation (TTT) diagram for an eutectoid carbon steel (Fig. 1), bearing in mind the fact that the pearlite reaction is essentially a high temperature one occurring between 550C and 720C and that the formation of the martensite is a low-temperature reaction, reveals that there is a wide range of temperature ∼250–550C within which neither of these phases for...
متن کاملDevelopment of Hard Bainite
The T0 temperature in steel is defined as that at which ferrite and austenite of the same chemical composition have identical free energy. The T0 temperature is that below which it is possible for austenite to transform to ferrite of the same chemical composition after allowing for the strain energy due to the displacements associated with the transformation. Bainite is expected below the T0 te...
