摘要: A method for creating an elongate passage of a desired cross-sectional shape and size within component. memory metal alloy is formed into element, such as wire (16), having the passage. The embedded component (10) manufactured, e.g., by laying-up from fiber/resin composite curing it, or casting in mold (50) liquid that hardens around alloy, embedding it place. may comprise glass, ceramic, thermoplastic, lower melting point than alloy. then pulled component, applying force sufficient to convert soft martensitic state stress-induced state, thereby plastically inelastically deforming so lengthens. As lengthens, its area decreases. In addition, conversion increases tensile strength, preventing being broken applied force. Due decrease diameter increase easily free leaving behind void substantially same wire.
