摘要： Described herein are fasteners and devices for securing together several components so that the load applied to the components is constant or nearly constant. The fasteners described herein include a hyperelastic member having first end to which a first retainer is coupled and a second end to which a second retainer is coupled. The retainers are configured to contact the structures being fastened and transfer the load from the structures to the hyperelastic member. The hyperelastic member may be an elongate shaft (e.g., a rod, cylinder, strut, etc.), and is a shape memory alloy that is typically fabricated as a single crystal.

摘要： A rotary actuator which provides a differential pulley pair having a shape memory alloy wire. The shape memory alloy wire is thermally cycled through its phase change transition temperature and contracts. Tension forces applied by the ends of the wires to opposite sides of the pulley pair result in a net torque which causes relative rotation between the pulley pair and a reference base. The large mechanical advantage of the differential pulley converts a large force working through a small distance into a relatively large angular rotation.

摘要： A temperature-activated valve for a conventional fire sprinkler utilizing a hyperelastic single-crystal shape memory alloy is described. The shape-memory element expands as it is heated, forcing a bolt to break, thereby opening the sprinkler valve. The devices described are less susceptible to accidental breakage than conventional actuators, and have fewer moving parts. Transition temperature of the shape memory alloy can be tuned to a narrow range.

摘要： Devices and methods of making devices having one or more components made of single crystal shape memory alloy capable of large recoverable distortions, defined herein as “hyperelastic” SMA. Recoverable Strains are as large as 9 percent, and in special circumstances as large as 22 percent. Hyperelastic SMAs exhibit no creep or gradual change during repeated cycling because there are no crystal boundaries. Hyperelastic properties are inherent in the single crystal as formed: no cold work or special heat treatment is necessary. Alloy components are Cu—Al—X where X may be Ni, Fe, Co, Mn. Single crystals are pulled from melt as in the Stepanov method and quenched by rapid cooling to prevent selective precipitation of individual elemental components. Conventional methods of finishing are used: milling, turning, electro-discharge machining, abrasion. Fields of application include aerospace, military, automotive, medical devices, microelectronics, and consumer products.

摘要： A microrelay device formed on a silicon substrate wafer for use in opening and closing a current path in a circuit. A pair of electrically conducting latching beams are attached at their proximal ends to terminals on the substrate. Proximal ends of the beams have complementary shapes which releasably fit together to latch the beams and close the circuit. A pair of shape memory alloy actuators are selectively operated to change shapes which bend one of the beams in a direction which latches the distal ends, or bend the other beam to release the distal ends and open the circuit. The microrelay is bistable in its two positions, and power to the actuators is applied only for switching it open or closed.

摘要： A non-explosive separation device for releasably holding together components of equipment or apparatus which are to be separated under controlled conditions. The separation device and method of operation includes a retaining element having a strain concentrated portion which completely cleaves when strained at a predetermined magnitude. Strain is applied to the retaining element by an actuating element which is comprised of a solid state phase change material having a shape memory. The actuating element is deformed to an armed shape at a temperature below the phase-change transition temperature. The device is activated by heating the actuating element through its transition temperature so that it recovers toward its memory shape. The retaining element is strained beyond its ultimate strength so that it cleaves at the strain concentrated portion. One embodiment of the invention provides a method for the non-destructive testing of the integrity and readiness of the separation device as well as a method of calibrating the release point of the device.

摘要： Shape-setting methods for fabricating devices made of single crystal shape memory alloys. The method include drawing a single crystal of a shape memory alloy from a melt of the alloy. This is followed by heating and quenching the crystal sufficiently rapid to limit the formation of alloy precipitates to an amount which retains hyperelastic composition and properties of the crystal.

摘要： Eyeglass frame hinges are replaced by flexures made of hyperelastic single-crystal shape memory alloy. These flexures exhibit more than 8 percent recoverable strain. Eyeglass frames with these flexures can be distorted repeatedly in ways that would destroy ordinary hinges, and recover without damage. Flexures may be incorporated in eyeglass frames in ways that make them attractive as fashion items, thus enhancing the value of a commodity consumer product.
