Solids produced as a result of a fast quench across a freezing or a
structural transition get stuck in long-lived metastable configurations of
distinct morphology, sensitively dependent on the processing history. {\it
Martensites} are particularly well studied examples of nonequilibrium
solid-solid transformations. Since there are some excellent reviews on the
subject, we shall, in this brief article, mainly present a summary of our work
on the nonequilibrium statistical mechanics of Martensites.Comment: 4 figs (3 embedded eps and 1 'slide.gif' separate), review written
