Abstract
We obtain insights into the athermal/isothermal martensite classification, and into puzzling delay times in athermal martensites, from Monte Carlo temperature-quench simulations of a discrete-strain pseudospin model for a square to rectangle transition.
► The same model gives athermal or isothermal regimes depending on parameters. ► A regime phase diagram in material parameters is explained in droplet picture. ► The isothermal C curves are drastically modified, by larger (and fewer) initial seeds. ► In the athermal regime, conversions can show delay tails, as in experiment. ► Delay times show Vogel–Fulcher divergences from closing conversion pathways.
