abstract = {<p style="text-align: justify;">We investigate the critical nucleus and equilibrium morphologies during
precipitation of a second-phase particle in a solid. We show that a combination of
diffuse-interface description and a constrained string method is able to predict both
the critical nucleus and equilibrium precipitate morphologies simultaneously without
a priori assumptions. Using the cubic to cubic transformation as an example, it is
demonstrated that the maximum composition within a critical nucleus can be either
higher or lower than that of equilibrium precipitate while the morphology of an equilibrium
precipitate may exhibit lower symmetry than the critical nucleus resulted from
elastic interactions.</p>},
