Atomic Mechanism of the Bainite Transformation

In order to design steels, it is not enough to simply look at the microstructure, but to be able to calculate it. In this lecture I will explain the way in which the atoms move during the bainite transformation and present some elementary thermodynamic and kinetic theory for the nucleation and growth of bainite. The difference between allotriomorphic ferrite, Widmanstaetten ferrite, upper and lower bainite, acicular ferrite and martensite will be explained in a quantitative framework.
