internal stress-induced nucleation is revealed. As shown in Fig 2, the sample without surface tension
transforms to the second martensitic variant while with surface tension transforms to the first
martensitic variant. The obtained results represent a much more detailed and precise model for coherent
solid-solid interface than current phenomenological models.
