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

摘要： A replacement for the conventional pyrotechnic separation device for large structural elements such as payload fairings on large missile systems is a sequence of nitinol wires or foil strips which, because of their high strength, will hold the structures together but, when heated electrically in sequence, will fuse in milliseconds to allow the structures to separate. The technique for fusing the wires sequentially is to provide wires of sequentially increasing lengths which will cause the shorter length, lower resistance wires to fuse first and the successively longer wires to fuse in sequence until all wires are fused.

摘要： A shape memory alloy used for both sensing and damping vibration of a structure. In one embodiment, a flat bar (12) is mounted from one end on its edge so that its other end vibrates from side-to-side at its natural resonant frequency. A vibration damping wire (30) extending longitudinally along one surface of the bar is mounted under tension between spaced apart standoffs (32); a sense wire (42) is similarly mounted along the opposite surface of the bar. The vibration damping wire and sense wire comprise a nickel-titanium (Nitinol) alloy, having a relatively high specific damping coefficient. Absorption of kinetic energy by the vibration damping wire when it is stretched by deflection of the bar greatly reduces the time required to passively damp vibration of the bar, compared to its undamped resonant time. the vibration damping wire is heated above a transition temperature by an electrical current pulse while relaxed to restore it to its unstretched length. The sense wire changes resistance in proportion to stress applied to the wire so that a voltage drop across the sense wire corresponds to the vibrational displacement of the bar. The voltage drop signal is used to control application of the current pulse in synchronization with the vibratory motion of the bar. To actively damp vibration of the bar, the pulse of electrical current is applied to heat the Nitinol alloy above its transition temperature so that it resumes a foreshortened memory shape as the bar's vibratory deflection tries to stretch the vibration damping wire. The vibration damping wire thus applies a force to the bar in opposition to its vibration. Other embodiments include a cylinder (52) and a vibration damped strut assembly (80). In these latter two embodiments, vibration damping wires and sense wires are disposed internally within the structure. A digital control (110) or analog vibration damping control (200) controls the application of current pulses to heat a selected vibration damping wire above the transition temperature in phase with the signal produced by the sensor wire.

摘要： A bearing having bearing elements made of Type 60 Nitinol made by an investment casting process for producing near net shape parts of Nitinol includes making a ceramic mold having a series of spherical cavities, pouring molten Nitinol into the mold cavities, cooling the mold and the Nitinol in the cavities to produce solidified Nitinol balls, and breaking the mold away from the Nitinol balls. Nitinol rods for roller bearings can be made by conventional casting directly from the crucible in a draw-down oven. The bars are hot machined or hot rotary swaged and then centerless ground and laser cut to length, or are first cut to length and then centerless ground individually for crowned roller elements. The balls are broken or cut from the risers, leaving the gates attached, and are consolidated by healing under pressure in a hot isostatic press, then ground to the desired size. The balls or rollers are polished, then treated to create an integral ceramic finish. They are then repolished to produce an extremely smooth finish. The balls can also be cut from a sheet or plate of the ball material as cubes or cylinders and processed in an abrasive tumbler to round off the corners and edges, and the rounded cubes or cylinders can hen be ground to spherical form in conventional ball grinder.

摘要： A projectile for being propelled toward a target includes a cylindrical body of Type 55 Nitinol that has a soft martensitic state that is readily deformed by rifling in the bore of a gun barrel to form grooves which ride on the rifling to spin the projectile. The Nitinol has a low coefficient of friction with the steel barrel and is sufficiently strong to prevent shedding particles or depositing projectile material in the bore. On impact with the target, the Nitinol undergoes a strain-induced shift to an ultra-high strength state in which the projectile is capable of remaining intact and concentrating its full energy on the small area of contact for maximal penetration and damage to the target instead of mushrooming widely and spreading its energy over a wide area as conventional projectiles do. Projectiles in the form of bullets, shotgun slugs, penetrating warheads, caseless ammunition and artillery shells are described.

摘要： A high security lock includes a shackle having two ends and a lock body having openings for receiving the ends of the shackle. A latch in the lock body has a catch movable into engagement with the shackle for securing at least one end of the shackle in the body. The latch is releasable to allow the one end of the shackle to move clear of the body to open the lock. The shackle is made of a shape memory effect alloy having a characteristic that its yield strength increases when work is impressed on it, so that cutting or breaking the shackle with common tools is more difficult and time consuming than with other shackle materials. The lock thus provides a level of security substantially superior to conventional locks.

摘要： A rotary actuator (18) is provided, including an actuator assembly (20). The actuator assembly includes a torque tube (24) formed of a shape memory alloy, a super elastic NiTinol return spring (26) having a proximal end (46) and a distal end (44), and a torque tube heating element (30) positioned near the torque tube. The torque tube (24) includes a proximal end (32) and a distal end (34). The return spring and torque tube are connected at their ends, with the torque tube being pretwisted while in a martensitic state relative to the spring. Activation of the heating element causes the torque tube to enter an austenitic state in which it returns to its previous untwisted configuration. Removal of heat allows the torque tube to return to a martensitic state, further allowing the return spring to retwist the torque tube. Further provided is a unique locking assembly (22) for use with the actuator assembly. Further provided is a helicopter blade twist rotation system for use with a rotor craft blade (200) having a blade root (202) and a tip (204). The system includes a shape memory alloy rotary actuator (18) located within the blade near the blade root, and a passive torque tube (206) located within the blade and having a proximal end connected to the rotary actuator and a distal end connected to the blade near to the blade tip.

摘要： A process for diffusion bonding a coating of Nitinol intermetallic compound to a surface of a metallic substrate includes heating and cleaning the surface of the substrate to a metallurgically clean condition by creating a plasma arc in a plasmatron and partially ionizing and heating a stream of inert gas in the plasma arc. The stream of partially ionized gas from the plasmatron is directed to the surface of the substrate to remove oxides and other contaminants from the surface. Nitinol powder is entrained in a mixture of hydrogen and argon gasses heated and ionized in the plasmatron, thereby heating the powder to a partially molten state. The partially molten power is ejected in the gas mixture from the plasmatron at high velocity and impacts against the metallurgically clean heated substrate surface to produce a diffusion bond between the Nitinol intermetallic compound and the metal substrate.

摘要： A process for making Type 60 Nitinol with shape memory effect from hot-worked material, such as hot rolled Type 60 Nitinol sheet or plate, includes heat treatment to a temperature of 600° C.–800° C. and holding the material at that temperature until the temperature has equalized throughout, and then heat soaking at that temperature for about 15 minutes. The material is then quenched immediately from that temperature, to a temperature below 300° C. This heat treatment produces Type 60 Nitinol in a condition denoted “ultraelastic”. Ultraelastic Type 60 Nitinol has a shape memory characteristic having a very low transition temperature. The transition temperature can be tailored within a wide temperature range by the temperature of the initial heat treatment and subsequent rate of cooling.
