Twin migration in Fe-based bcc crystals: theory and experiments
We establish an overall energy expression to determine the twin migration stress in bcc metals. Twin migration succeeds twin nucleation often after a load drop, and a model to establish twinExpand

Shape memory strains and temperatures in the extreme
It is well known that the achievement of high transformation strains in shape memory alloys (SMAs) has been curtailed by plastic deformation mediated via dislocation slip. In particular, theExpand
