  • Article using shape-memory alloy to improve and/or control the speed of recovery
    Patent number: 4839479
    Abstract: An article in the form of a projectile, a shock-sensitive switch or a sabot having an active component of shape-memory alloy which exhibits the shape-memory effect to provide a mechanical movement in response to a pressure wave passing through the article is disclosed. A thermal enhancement component which rapidly generates heat to initiate the shape-memory effect is also disclosed.
    Type: Grant
    Filed: July 18, 1988
