===Kinetics===
{{Main|Chemical kinetics}}
[[Chemical kinetics]] is the study of the rates at which systems that are out of equilibrium change under the influence of various forces. When applied to materials science, it deals with how a material changes with time (moves from non-equilibrium to equilibrium state) due to application of a certain field. It details the rate of various processes evolving in materials including shape, size, composition and structure. [[Diffusion]] is important in the study of kinetics as this is the most common mechanism by which materials undergo change.<ref>{{Cite book |last1=Kärger |first1=Jörg |url=http://dx.doi.org/10.1002/9783527651276 |title=Diffusion in Nanoporous Materials |last2=Ruthven |first2=Douglas M. |last3=Theodorou |first3=Doros N. |date=2012-04-25 |publisher=Wiley |doi=10.1002/9783527651276 |isbn=978-3-527-31024-1}}</ref> Kinetics is essential in processing of materials because, among other things, it details how the microstructure changes with application of heat.
