It is in this annular cavity 46 between the opposing annular surfaces 42 and 44 that the locking memory member 25 is disposed in accordance with the invention.
- the memory locking member 25 may typically be provided in the form of a ring or washer with serrated outer surfaces 25a and also advantageously including circumferentially spaced memory tabs 25b extending therefrom.
- the memory locking member 25 is made of a material having controllable mechanical memory properties.
- the memory material is preferably a metallic alloy comprising an equiatomic nickel-titanium intermetallic compound containing approximately 53 to 57 percent by weight of nickel with the balance titanium. This alloy is customarily referred to in the art as 55-Nitinol.
- alloys such as 55-Nitinol are only partially understood in the art, and are believed to be a result of a reversible stressinduced, martensitic transformation.
- An original memory shape may be set into the alloy at an elevated temperature which is typically about 900F for 55-Nitinol.
- This original shape will be retained after the alloy is cooled.
- the alloy may then be deformed to a desired intermediate shape.
- Return to the original shape may then be subsequently accomplished when desired by the application of moderate amounts of heat to bring the alloy to a predetermined transitional temperature range which may be varied by appropriate choice of the particular alloy composition.
- a transitional temperature range of 60F to 300F may be provided by appropriately changing the percentage of nickel and/or substituting cobalt for nickel on an atomfor-atom basis.
- the shape recovery temperature range is also dependent on the specific processing history of the alloy. During return of the alloy to its original shape, very considerable force can be exerted thereby so that much mechanical work can be accomplished. Further details concerning SS-Nitinol can be obtained from the article What You Can Do With That Memory Alloy, Materials Engineering, 70, pp. 28-31 (October 1969).
- the particular original and intermediate shapes chosen for the locking memory member 25 will now be considered in more detail, the intermediate shape being illustrated in FIGS. 13 and the original shape being illustrated in FIGS. 4 and 5.
- the locking memory member 25 is typically set in accordance with the invention to an original shape having a slightly bowed cross-section with the four circumferentially spaced memory tabs 250 being bent so as to extend radially therefrom as shown.
