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.4 figs (3 embedded eps and 1 'slide.gif' separate), review written for Current ScienceStatistical MechanicsMaterials ScienceArrested States of Solidstext
