  • Superelastic Alloy Structural Geometry for Ultrahigh Mechanical Damping
    Publication number: 20150337420
    Abstract: A mechanical structure is provided with a crystalline super alloy that is characterized by an average grain size and that exhibits 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 undergoes the martensitic transformation without intergranular fracture of the geometric feature.
    Type: Application
    Filed: June 24, 2015
    Publication date: November 26, 2015
    Applicant: MASSACHUSETTS INSTITUTE OF TECHNOLOGY
