Abstract:
A mechanical structure is provided with a crystalline superelastic alloy that is characterized by an average grain size and that is characterized by a martensitic phase transformation resulting from a mechanical stress input greater than a characteristic first critical stress. A configuration of the superelastic alloy is provided with a geometric structural feature of the alloy that has an extent that is no greater than about 200 micrometers and that is no larger than the average grain size of the alloy. This geometric feature is configured to accept a mechanical stress input.
