Theory of transformations

We deal mostly with phase changes which are thermodynamically of first order, i.e. they involve nucleation and growth with well-defined mechanisms of transformations and particular constraints to the achievement of equilibrium. In fact, most useful microstructures are far from equilibrium so we build kinetic theory to determine non-equilibrium states. There are complications when many different transformations occur together, complications which have stimulated new theory. Finally, the microstructure must be related to properties which are appreciated by technologists.

Mathematical models

We express the theory and empirical observations in the form of computer models which can be used to greatly reduce the vast number of parameters that have to be controlled during the creation of new alloys and processes. We also produce courses, books and algorithms in addition to research papers to help spread the word about this thriving science of materials
