In a method for expanding the hysteresis loop of an article comprised a metallic composition capable of undergoing a reversible transformation between austenitic and martensitic states wherein the As of the compn. is elevated above its normal As, the method includes deforming the article from an original configuration into a second deformed configuration from which heat recovery towards the original configuration is desired, the recovery begins above the normal As of the metal composition, when the constraining means is removed and removing the constraining means.
