  • Patent number: 10364483
    Abstract: One or more substitutional elements may be used to reduce the solution treatment temperature and required quench rates for hardening of 60-NITINOL. The advantages of modified NITINOL include that less energy is consumed during the heat treatment process, the material is subjected to less thermal distortion, and less machining is required. Modified NITINOL may have adequate hardness for bearing applications and may display highly elastic behavior.

  • Patent number: 9393619
    Abstract: Disclosing herein is a method for manufacturing nickel-titanium compositions. The method includes disposing a powdered composition in a mold; the powdered composition comprising nickel and titanium; the titanium being present in an amount of about 38 to about 42 wt % and the nickel being present in an amount of about 58 to about 62 wt %; sintering the powdered composition to produce a sintered preform; compacting the preform; machining the preform to form an article; heat treating the article; the annealing being conducted at a temperature of about 1650° F. to about 1900° F. at a pressure of about 3 Torr to about 5 Kg?f/cm2 for a time period of about 10 minutes to about 5 hours; and quenching the article.

  • Patent number: 9169545
    Abstract: A material for use as a mechanical component is formed of a superelastic intermetallic material having a low apparent modulus and a high hardness. The superelastic intermetallic material is conditioned to be dimensionally stable, devoid of any shape memory effect and have a stable superelastic response without irrecoverable deformation while exhibiting strains of at least 3%. The method of conditioning the superelastic intermetallic material is described. Another embodiment relates to lightweight materials known as ordered intermetallics that perform well in sliding wear applications using conventional liquid lubricants and are therefore suitable for resilient, high performance mechanical components such as gears and bearings.

  • Patent number: 8709176
    Abstract: A method and an apparatus confer full superelastic properties to the active surface of a mechanical component constructed of a superelastic material prior to service. A compressive load is applied to the active surface of the mechanical component followed by removing the compressive load from the active surface whereby substantially all load strain is recoverable after applying and removing of subsequent compressive loads.

  • Patent number: 6007068
    Abstract: A radial face seal arrangement is disclosed comprising a stationary seal g that is spring loaded against a seal seat affixed to a rotating shaft. The radial face seal arrangement further comprises an arrangement that not only allows for preloading of the stationary seal ring relative to the seal seat, but also provides for dampening yielding a dynamic sealing response for the radial face seal arrangement. The overall seal system, especially regarding the selection of the material for the stationary seal ring, is designed to operate over a wide temperature range from below ambient up to 900.degree. C.
