Pseudoelasticity in Fe3Ga single crystals

We first found pseudoelasticity in Fe3Ga single crystals regardless of a thermoelastic martensitic transformation. Superpartial dislocations with Burgers vector of 1/4[1 1 1] were pulled back by nearest-neighbour and next-nearest-neighbour antiphase boundaries during unloading, resulting in the pseudoelasticity.
