Definitions
- the present disclosure relates generally to devices for fastening components to each other. More specifically, but not by way of limitation, this disclosure relates to a fastener actuated by a shape-memory alloy.
- One or more fasteners can mechanically interlock two or more components of a system together.
- Fasteners can be releasable. That is, some fasteners can be selectively disengaged to free the interlocked components from one another.
- fasteners can be actuated (i.e., selectively engaged or disengaged) by hand, motor, or by applying hydraulic pressure to the fastener. Actuating a fastener by hand, however, can be impractical or impossible when the fastener is in a remote location, such as in a wellbore.
- Actuating a fastener via a motor can be inefficient and impractical, as motors can be large in size, expensive, prone to mechanical failures, and require significant power for operation. Further, actuating a fastener via hydraulic pressure can be too time consuming and uncontrollable for some applications. Accordingly, it can be challenging to quickly, remotely, and selectively actuate a fastener.
- FIG. 1 is a cross-sectional view of one embodiment of a well system that can include a shape-memory alloy actuated fastener according to one embodiment of the present disclosure.
- FIG. 2 is a cross-sectional side view of a well system component shown in FIG. 1 according to one embodiment of the present disclosure.
- FIG. 4 is a cross-sectional side view of the shape-memory alloy actuated fastener shown in FIG. 3 in a second position according to one embodiment of the present disclosure.
- FIG. 5 is a cross-sectional side view of the well system component shown in FIG. 2 in which the shape-memory alloy actuated fastener has released a receiving component according to one embodiment of the present disclosure.
- FIG. 6 is a cross-sectional side view of a well system component with a shape-memory alloy actuated fastener according to another embodiment of the present disclosure.
- FIG. 7 is a perspective view of the shape-memory alloy actuated fastener in the well-system component of FIG. 6 according to one embodiment of the present disclosure.
- FIG. 8 is a perspective view of a system with a shape-memory alloy actuated fastener according to another embodiment of the present disclosure.
- FIG. 9 is a flow chart of an example of a process for using a shape-memory alloy actuated fastener according to one embodiment.
- the shape-memory alloy actuated fastener can be, or can be included in, a latch (e.g., a collet latch or C-latch), bolt, lug, clamp, spring, threaded connector, dog, or wire.
- the shape-memory alloy actuated fastener can include a shape-memory alloy.
- a shape-memory alloy can include an alloy of metals with atoms that can be arranged in two different crystal structures. Each crystal structure can define a physical shape for the shape-memory alloy.
- the atoms can be arranged in one crystal structure, which can define one physical shape (i.e., the low-temperature shape) for the shape-memory alloy.
- the atoms When heated above a transition temperature, the atoms can rearrange to the other crystal structure, which can define another physical shape (i.e., the high-temperature shape) for the shape-memory alloy.
- the shape-memory alloy can substantially revert back to its low-temperature shape when cooled back below the transition temperature.
- the shape-memory alloy can change between two physical shapes. Because the fastener can include the shape-memory alloy, the fastener can change between two physical shapes upon the heating or cooling of the fastener.
- the fastener can be configured for selectively interlocking or releasing (i.e., engaging or disengaging) multiple components.
- the fastener's low-temperature shape can be configured to interlock multiple components.
- the fastener's high-temperature shape can be configured to release the multiple components from one another.
- the fastener can interlock multiple components when in its low-temperature shape. When heated above a transition temperature, the fastener can change into its high-temperature shape and release the multiple components from one another. In some embodiments, when cooled back below the transition temperature, the fastener can change substantially back into its low-temperature shape, which can again interlock the multiple components.
- the fastener can be actuated by selectively heating or cooling the fastener.
- the fastener's high-temperature shape and low-temperature shape can be reversed. That is, in some embodiments, the fastener's high-temperature shape can be configured to interlock multiple components, while the fastener's low-temperature shape can be configured to release the multiple components from one another.
- the shape-memory alloy actuated fastener can be a part of a valve deployed in a wellbore.
- a wellbore is a hole drilled in a subterranean formation as part of a well system (e.g., for extracting fluid or gas from the subterranean formation).
- the valve can control the flow of fluid or gas through the wellbore.
- the valve can include a shape-memory alloy actuated fastener which, when in its low-temperature shape, can interlock multiple valve components to effectively close the valve. When closed, the valve can prohibit fluid or gas from flowing through the wellbore.
- a temperature-control device for example a heating blanket, can be positioned within the valve or otherwise thermally coupled to the shape-memory alloy actuated fastener.
- a well operator can operate the temperature-control device, for example, by transmitting power to the temperature-control device.
- the temperature-control device can heat the shape-memory alloy actuated fastener above a transition temperature, which can cause the shape-memory alloy actuated fastener to change its physical shape to its high-temperature shape.
- the shape-memory alloy actuated fastener Upon changing to its high-temperature shape, the shape-memory alloy actuated fastener can release the valve components to effectively open the valve. When open, the valve can permit fluid or gas to flow through the well system.
- the temperature-control device can cool the shape-memory alloy actuated fastener back below the transition temperature, which can cause the shape-memory alloy actuated fastener to substantially change its physical shape back into its low-temperature shape. In this way, the well operator can quickly, remotely, and selectively control the valve via the shape-memory alloy actuated fastener.
- a shape-memory alloy actuated fastener can be used in a variety of other contexts to perform numerous functions.
- a shape-memory alloy actuated fastener can be used with, or be a part of, an automobile, aircraft, boat, computer, appliance, furniture piece, machine, toy, sports equipment, electrical system, or other device.

Description
- This is a continuation of U.S. patent application Ser. No. 14/653,931, titled “Shape-Memory Alloy Actuated Fastener” and filed Jun. 19, 2015, which is a U.S. national phase under 35 U.S.C. § 371 of International Patent Application No. PCT/US2014/044832, titled “Shape-Memory Alloy Actuated Fastener” and filed Jun. 30, 2014, the entirety of each which is hereby incorporated by reference herein.
- The present disclosure relates generally to devices for fastening components to each other. More specifically, but not by way of limitation, this disclosure relates to a fastener actuated by a shape-memory alloy.
- One or more fasteners (e.g., latches, bolts, lugs, and clamps) can mechanically interlock two or more components of a system together. Fasteners can be releasable. That is, some fasteners can be selectively disengaged to free the interlocked components from one another. Typically, fasteners can be actuated (i.e., selectively engaged or disengaged) by hand, motor, or by applying hydraulic pressure to the fastener. Actuating a fastener by hand, however, can be impractical or impossible when the fastener is in a remote location, such as in a wellbore. Actuating a fastener via a motor can be inefficient and impractical, as motors can be large in size, expensive, prone to mechanical failures, and require significant power for operation. Further, actuating a fastener via hydraulic pressure can be too time consuming and uncontrollable for some applications. Accordingly, it can be challenging to quickly, remotely, and selectively actuate a fastener.

FIG. 8 is a perspective view of a system with a shape-memory alloy actuated fastener according to another embodiment of the present disclosure. -
FIG. 9 is a flow chart of an example of a process for using a shape-memory alloy actuated fastener according to one embodiment. - Certain aspects and features of the present disclosure are directed to a shape-memory alloy actuated fastener. The shape-memory alloy actuated fastener can be, or can be included in, a latch (e.g., a collet latch or C-latch), bolt, lug, clamp, spring, threaded connector, dog, or wire. The shape-memory alloy actuated fastener can include a shape-memory alloy. A shape-memory alloy can include an alloy of metals with atoms that can be arranged in two different crystal structures. Each crystal structure can define a physical shape for the shape-memory alloy. At colder temperatures, the atoms can be arranged in one crystal structure, which can define one physical shape (i.e., the low-temperature shape) for the shape-memory alloy. When heated above a transition temperature, the atoms can rearrange to the other crystal structure, which can define another physical shape (i.e., the high-temperature shape) for the shape-memory alloy. In some embodiments, the shape-memory alloy can substantially revert back to its low-temperature shape when cooled back below the transition temperature. By heating or cooling the shape-memory alloy, the shape-memory alloy can change between two physical shapes. Because the fastener can include the shape-memory alloy, the fastener can change between two physical shapes upon the heating or cooling of the fastener.
- The fastener can be configured for selectively interlocking or releasing (i.e., engaging or disengaging) multiple components. For example, in some embodiments, the fastener's low-temperature shape can be configured to interlock multiple components. The fastener's high-temperature shape can be configured to release the multiple components from one another. The fastener can interlock multiple components when in its low-temperature shape. When heated above a transition temperature, the fastener can change into its high-temperature shape and release the multiple components from one another. In some embodiments, when cooled back below the transition temperature, the fastener can change substantially back into its low-temperature shape, which can again interlock the multiple components. In this way, the fastener can be actuated by selectively heating or cooling the fastener. Further, in some embodiments, the fastener's high-temperature shape and low-temperature shape can be reversed. That is, in some embodiments, the fastener's high-temperature shape can be configured to interlock multiple components, while the fastener's low-temperature shape can be configured to release the multiple components from one another.
- In one example, the shape-memory alloy actuated fastener can be a part of a valve deployed in a wellbore. A wellbore is a hole drilled in a subterranean formation as part of a well system (e.g., for extracting fluid or gas from the subterranean formation). The valve can control the flow of fluid or gas through the wellbore. The valve can include a shape-memory alloy actuated fastener which, when in its low-temperature shape, can interlock multiple valve components to effectively close the valve. When closed, the valve can prohibit fluid or gas from flowing through the wellbore. A temperature-control device, for example a heating blanket, can be positioned within the valve or otherwise thermally coupled to the shape-memory alloy actuated fastener. A well operator can operate the temperature-control device, for example, by transmitting power to the temperature-control device. The temperature-control device can heat the shape-memory alloy actuated fastener above a transition temperature, which can cause the shape-memory alloy actuated fastener to change its physical shape to its high-temperature shape. Upon changing to its high-temperature shape, the shape-memory alloy actuated fastener can release the valve components to effectively open the valve. When open, the valve can permit fluid or gas to flow through the well system. In some embodiments, the temperature-control device can cool the shape-memory alloy actuated fastener back below the transition temperature, which can cause the shape-memory alloy actuated fastener to substantially change its physical shape back into its low-temperature shape. In this way, the well operator can quickly, remotely, and selectively control the valve via the shape-memory alloy actuated fastener.
- Although the shape-memory alloy actuated fastener was described in the above example as part of a well-system component, a shape-memory alloy actuated fastener can be used in a variety of other contexts to perform numerous functions. For example, in some embodiments, a shape-memory alloy actuated fastener can be used with, or be a part of, an automobile, aircraft, boat, computer, appliance, furniture piece, machine, toy, sports equipment, electrical system, or other device. Further, embodiments can include multiple shape-memory alloy actuated fasteners configured in any number of ways.
- These illustrative examples are given to introduce the reader to the general subject matter discussed here and are not intended to limit the scope of the disclosed concepts. The following sections describe various additional features and examples with reference to the drawings in which like numerals indicate like elements, and directional descriptions are used to describe the illustrative aspects but, like the illustrative aspects, should not be used to limit the present disclosure.

FIG. 1 is a cross-sectional view of one embodiment of awell system 100 that can include a shape-memory alloy actuated fastener according to one embodiment of the present disclosure. Thewell system 100 includes awellbore 102. In some embodiments, thewellbore 102 can be cased and cemented, as shown inFIG. 1 . In other embodiments, thewellbore 102 can be uncased or the casing may not be cemented. - The
wellbore 102 can include atubular string 104, for example, a lower completion assembly. Thetubular string 104 can be positioned in thelower portion 112 of thewellbore 102.Annulus 110 can be formed between thetubular string 104 and thewellbore 102. - The
wellbore 102 can also include a well-system component 108, for example, an isolation barrier valve, packer, plug, sliding sleeve, running tool, setting tool latching tool, shear joint, travel joint, or another type of valve (e.g., a safety valve, flapper valve, or ball valve). In some embodiments, the well-system component 108 can include a shape-memory alloy actuated fastener (discussed further with respect toFIG. 2 ). The well-system component 108 can also include a temperature-control device (e.g., a heating device or cooling device) for actuating the shape-memory alloy actuated fastener. - The
wellbore 102 can further include anothertubular string 106, for example, an upper completion assembly. Thetubular string 106 can be positioned in theupper portion 114 of thewellbore 102. Although depicted in this example as connected to the well-system component 108, in some embodiments, thetubular string 106 can be disconnected from the well-system component 108. Further, some embodiments may not include thetubular string 104 or thetubular string 106, and may include other well-system components. -
FIG. 2 is a cross-sectional side view of the well-system component 108 shown inFIG. 1 according to one embodiment of the present disclosure. In some embodiments, the well-system component 108 is, or can include, a valve, for example, an isolation barrier valve. An isolation barrier valve can isolate the lower portion of the wellbore from an upper portion of the wellbore, which can prevent or minimize fluid or gas communication between the lower portion of the wellbore and the upper portion of the wellbore. - The well-
system component 108 can include ahousing 202. Atube 204 can be disposed within thehousing 202 for communicating fluid or gas through the well-system component 108. Further, the well-system component 108 can include a shape-memory alloy actuatedfastener 206, for example, the shape-memory alloy actuatedfastener 206 depicted inFIG. 3 . -
FIG. 3 is a cross-sectional side view of a shape-memory alloy actuatedfastener 206 in a first position according to one embodiment of the present disclosure. In this example, the shape-memory alloy actuatedfastener 206 is a collet latch. - The shape-memory alloy actuated
fastener 206 can include abody 306. In some embodiments, thebody 306 can include a ring shape. In other embodiments, thebody 306 can include another shape, for example a square, triangular, rectangular, or trapezoidal shape. In some embodiments, thebody 306 can include a cavity, for example, for allowing one or more components to fit through thebody 306. - An annular array of
fingers 302 can extend from an end of thebody 306. In this example, the annular array offingers 302 extends from both ends of thebody 306. Thefingers 302 can include enlarged ends 304. In some embodiments, the enlarged ends 304 can be positioned on the ends of thefingers 302. The enlarged ends 304 can releaseably interlock with a component, for example, a component of a valve in a wellbore. In some embodiments, the enlarged ends 304 can include a back-angle configuration for interlocking with a component. That is, the enlarged ends 304 can angle backwards towards thebody 306 of the shape-memory alloy actuatedfastener 206. In other embodiments, the enlarged ends 304 can include other configurations for interlocking with a component, for example, a 90-degree configuration. A 90-degree configuration can include enlarged ends 304 that extend perpendicularly (i.e., 90 degrees) from thefingers 302. - The shape-memory alloy actuated
fastener 206 can include a shape-memory alloy, which can include, for example, nickel (Ni), titanium (Ti), copper (Cu), aluminum (Al), zinc (Zn), iron (Fe), manganese (Mn), silicon (Si), hafnium (Hf), palladium (Pd), or gold (Au). In some embodiments, the shape-memory alloy actuatedfastener 206 can include, for example, Ni—Ti, Ni—Al, Cu—Al—Ni, Cu—Zn—Al, Fe—Mn—Si, Fe—Ni—Co—Ti, Ni—Ti—Hf, or Ni—Ti—Pd. - In some embodiments, the entire shape-memory alloy actuated
fastener 206 can include a shape-memory alloy. In other embodiments, one or more parts of the shape-memory alloy actuatedfastener 206, for example thefingers 302 and/or the enlarged ends 304, can include the shape-memory alloy. - In some embodiments, one or more parts of the shape-memory alloy actuated
fastener 206 that directly releasably couple with a component can include the shape-memory alloy. For example, in some embodiments, the enlarged ends 304 of the shape-memory alloy actuatedfastener 206 can include a shape-memory alloy, and can directly interlock with or release a component. In other embodiments, the shape-memory alloy can cause (e.g., directly or indirectly) a part of the shape-memory alloy actuatedfastener 206, which may not include the shape-memory alloy, to releaseably couple with a component. For example, thebody 306 of the shape-memory alloy actuatedfastener 206 can include a shape-memory alloy. The shape-memory alloy can be configured to cause the annular array offingers 302 and the enlarged ends 304, which may not include a shape-memory alloy, to releaseably couple with a component. In some embodiments, the shape-memory alloy can push, pull, move, or otherwise interact with a part of the shape-memory alloy actuatedfastener 206, which can cause the shape-memory alloy actuatedfastener 206 to releaseably interlock with a component. - Further, in some embodiments, the shape-memory alloy actuated
fastener 206 can include multiple shape-memory alloys. For example, in some embodiments, the shape-memory alloy actuatedfastener 206 can include multiple shape-memory alloys with different transition temperatures. Different components of the shape-memory alloy actuatedfastener 206 can be actuated at different times by applying different amounts of heat to the shape-memory alloy actuatedfastener 206. - Returning to
FIG. 2 , the shape-memory alloy actuatedfastener 206 can interlock with a receivingcomponent 208, for example, a latch crossover. When the shape-memory alloy actuatedfastener 206 is interlocked with the receivingcomponent 208, the receivingcomponent 208 can keep a closure component (e.g., a ball) in the well-system component 108 in a closed position. This can close the well-system component 108, which can, for example, prevent or minimize fluid or gas communication through the well-system component 108. - Further, the well-
system component 108 can also include apower supply 214, for example, one or more C-sized batteries. Although thepower supply 214 is depicted in this example as disposed within the well-system component 108, in other embodiments, thepower supply 214 can be positioned elsewhere, for example, thepower supply 214 can be coupled to other well-system components or positioned aboveground. - An operator (e.g., a well operator) can control the
power supply 214. In some embodiments, an operator can control thepower supply 214 via a computing device (not shown), which can be in communication with thepower supply 214. The computing device can include a processor interfaced with other hardware via a bus. A memory, which can include any suitable tangible (and non-transitory) computer-readable medium such as RAM, ROM, EEPROM, or the like, can include program components that configure operation of the computing device. The computing device can also include input/output interface components and additional storage. - Further, each of the computing device and the
power supply 214 can include a communication device (not shown) for communicating with one another. In some embodiments, the communication device can include one or more of any components that facilitate a network connection. For example, in some embodiments, the communication device can be wireless and can include wireless interfaces such as IEEE 802.11, Bluetooth, or radio interfaces for accessing cellular telephone networks (e.g., transceiver/antenna for accessing a CDMA, GSM, UMTS, or other mobile communications network). In other embodiments, the communication device can be wired and can include interfaces such as Ethernet, USB, or IEEE 1394. - The
power supply 214 can be in communication with a temperature-control device 212, for example a heating blanket (e.g., a ceramic heating blanket). The temperature-control device 212 can be coupled to or in thermal communication with the shape-memory alloy actuatedfastener 206. In some embodiments, anarea 216 surrounding the temperature-control device 212 can be insulated, for example, to prevent heat loss. Upon receiving the power from thepower supply 214, the temperature-control device 212 can heat or cool the shape-memory alloy actuatedfastener 206. This can cause the shape-memory alloy actuatedfastener 206 to change its physical shape, for example, as shown inFIG. 4 . -
FIG. 4 is a cross-sectional side view of the shape-memory alloy actuated fastener shown inFIG. 3 in a second position according to one embodiment of the present disclosure. In some embodiments, one or more fingers in the annular array offingers 302 in the shape-memory alloy actuatedfastener 206 can bend radially outward. This can increase the diameter of the annular array offingers 302. In other embodiments, one or more of the fingers in the annular array offingers 302 can bend radially inward, which can decrease the diameter of the annular array offingers 302. Further, in some embodiments, the length or width of one or more of the fingers in the annular array offingers 302 can increase or decrease or size. - Further, in some embodiments, the
body 306 or the enlarged ends 304 can change physical shape, for example, to enhance the decoupling or releasing of a component. For example, in some embodiments, the enlarged ends 304 can change shape from a back-angled configuration to a 90-degree configuration. Any number of shape-memory alloy actuatedfastener 206 parts can change physical shape at any number of transition temperatures, and any configuration of physical shapes may be possible. - Returning again to
FIG. 2 , as noted above, upon receiving the power from thepower supply 214, the temperature-control device 212 can cause the shape-memory alloy actuatedfastener 206 to change shape (e.g., change to its high-temperature shape). As the shape-memory alloy actuatedfastener 206 changes shape, the shape-memory alloy actuatedfastener 206 can release from the receivingcomponent 208, for example, as shown inFIG. 5 . In some embodiments, the shape-memory alloy actuatedfastener 206 and/or the receivingcomponent 208 can be coated with a low friction coating, for example, to enhance the decoupling or releasing of the shape-memory alloy actuatedfastener 206 from the receivingcomponent 208. - Upon the shape-memory alloy actuated
fastener 206 releasing the receivingcomponent 208, in some embodiments, the receivingcomponent 208 can move, for example, to a different position (e.g., to the right as viewed in each ofFIGS. 2 and 6 ). In some embodiments, pressure, gravity, springs, or other means can aid in thereceiving component 208 moving to the different position. In some embodiments, when in the different position, the receivingcomponent 208 can keep the closure component in the well-system component 108 in an open position. This can allow fluid or gas communication through the well-system component 108. Unlike with traditional well-system components (e.g., a traditional isolation barrier valve), which can rely on slow, inefficient, and unpredictable hydraulic pressure cycling for remote actuation, in some embodiments, an operator can remotely, quickly, and selectively actuate a well-system component 108 via a shape-memory alloy actuatedfastener 206. - In some embodiments, the well-
system component 108 can include additional, fewer, or different components. For example, the well-system component 108 can include any number or configuration of shape-memory alloy actuatedfasteners 206, a piston, spring (e.g., a power spring), washer, O-ring, seal, hydraulic power assembly or component, screw, transducer, housing, or lock ring. Further, in some embodiments, the well-system component 108 can include anindexing mandrel 210, which is radially positioned between thehousing 202 and thetube 204. Theindexing mandrel 210 can be used for actuating a well-system component 108 via hydraulic pressure cycling. In some embodiments, an operator can use multiple actuation systems (e.g., a shape-memory alloy actuatedfastener 206 and hydraulic pressure cycling) for operating the well-system component 108. -
FIG. 6 is a cross-sectional side view of the well-system component 108 with a shape-memory alloy actuated fastener according to another embodiment of the present disclosure. In some embodiments, the well-system component 108 ofFIG. 6 is, or can include, a valve, for example, an isolation barrier valve. The well-system component 108 ofFIG. 6 can also include thehousing 202, thetube 204, theindexing mandrel 210, the temperature-control device 212, and thepower supply 214, which can be configured substantially the same ofFIG. 6 as described with respect toFIG. 2 . Further, the well-system component 108 can include a shape-memory alloy actuatedfastener 602, for example, the shape-memory alloy actuated fastener shown inFIG. 7 . -
FIG. 7 is a perspective view of the shape-memory alloy actuatedfastener 602 in the well-system component 108 ofFIG. 6 according to one embodiment of the present disclosure. In this example, the shape-memory alloy actuatedfastener 602 is a C-ring. - The shape-memory alloy actuated
fastener 602 can include abody 704. In some embodiments, thebody 704 can include a cylindrical shape. Disposed within thebody 704 can be a cylindrically-shapedcavity 710, such that the end of thebody 704 includes a ring shape. In other embodiments, thebody 704 can include another shape, for example a square, triangular, rectangular, or trapezoidal shape. In some embodiments, thebody 704 can include a cavity, for example, for allowing one or more components to fit through thebody 704. - A
connector 706 can extend from the end of thebody 704. Theconnector 706 can join the cross-sectional end of thebody 704 to a lockingmember 708. In some embodiments, the lockingmember 708 can.include a C-shape. In other embodiments, the lockingmember 708 can include another shape, for example, a square, ring, circle, triangle, rectangle, or trapezoid shape. - In some embodiments, the entire shape-memory alloy actuated
fastener 602 can include a shape-memory alloy. In other embodiments, one or more parts (i.e., components) of the shape-memory alloy actuatedfastener 602, for example thebody 704 or the lockingmember 708, can include one or more shape-memory alloys. Further, in some embodiments, the shape-memory alloy actuatedfastener 602 may not include thebody 704 or theconnector 706. That is, in some embodiments, the shape-memory alloy actuatedfastener 602 can only include the lockingmember 708. - Returning to
FIG. 6 , in some embodiments, one piece of the shape-memory alloy actuated fastener 602 (e.g., the body 704) can be coupled to thewell component 606. Another piece of the shape-memory alloy actuated fastener 602 (e.g., the locking member 708) can interlock with a receivingcomponent 604. When the shape-memory alloy actuatedfastener 602 is interlocked with the receivingcomponent 604, the receivingcomponent 604 can keep a closure component (e.g., a ball) in the well-system component 108 ofFIG. 6 in a closed position. This can close the well-system component 108 ofFIG. 6 , which can prevent or minimize fluid or gas communication through the well-system component 108. - The well-
system component 108 ofFIG. 6 can also include the temperature-control device 212 in communication with thepower supply 214, as described with respect toFIG. 2 . An operator can actuate thepower supply 214, which can transmit power to the temperature-control device 212. The temperature-control device 212 can heat or cool the shape-memory alloy actuatedfastener 602, which can cause the shape-memory alloy actuatedfastener 602 to change into another physical shape, for example, to its high-temperature shape. In some embodiments, the high-temperature shape can include a physical shape in which a piece of the shape-memory alloy actuated fastener 602 (e.g., the locking member 708) has radially expanded or increased in diameter. Upon changing its physical shape, the shape-memory alloy actuatedfastener 602 can release thewell component 606 from the receivingcomponent 604. In some embodiments, this can cause thewell component 606 to be able to move, for example, to a different position (e.g., to the right as viewed inFIG. 6 ). In some embodiments, pressure, gravity, springs, or other means can aid in thewell component 606 moving to the different position. In some embodiments, when in the different position, thewell component 606 can keep the closure component (not shown) in the well-system component 108 ofFIG. 6 in an open position. This can allow fluid or gas communication through the well-system component 108 ofFIG. 6 . - Further, in some embodiments, multiple shape-memory alloy actuated
fasteners 602 can be used in sequence or in concert. For example, multiple shape-memory alloy actuatedfasteners 602 with the same transition temperature, different transition temperatures, or that interlock different combinations of components can be used in sequence or in concert. For example, in some embodiments, the well-system component 108 ofFIG. 6 can include multiple shape-memory alloy actuatedfasteners 602 actuated by different transition temperatures. Actuating the multiple shape-memory alloy actuatedfasteners 602 at different times via different transition temperatures can provide greater control over actuation of the well-system component 108 ofFIG. 6 . -
FIG. 8 is a perspective view of asystem 800 with a shape-memory alloy actuated fastener according to another embodiment of the present disclosure. In some embodiments, thesystem 800 can include anelectrical component 810. Theelectrical component 810 can include, for example, a computer, cellular telephone, resistor, capacitor, inductor, integrated circuit component, power supply, processor, microcontroller, memory, or motor. Theelectrical component 810 can be coupled to a conductor 802 (e.g., a wire or circuit board trace). Theconductor 802 can include any suitable conductive material, for example, copper, tin, iron, aluminum, gold, or silver. Anotherelectrical component 810 can be coupled to another conductor 804 (e.g., a wire or circuit board trace). Theconductor 804 can include any suitable conductive material, for example, copper, tin, iron, aluminum, gold, or silver. - In some embodiments, the
conductors fastener 806. Further, in some embodiments, theconductors fastener 806. The shape-memory alloy actuatedfastener 806 can include a shape-memory alloy that includes any conductive material, for example, copper. In the example shown inFIG. 8 , the shape-memory alloy actuatedfastener 806 includesclasps 808 for releasably coupling theconductors clasps 808 can include a shape-memory alloy. In other embodiments, the shape-memory alloy actuatedfastener 806 may not include theclasps 808. - In some embodiments, the
system 800 can also include a temperature-control device 812. Thetemperature control device 812 can be in communication with apower supply 814. In some embodiments, an operator can actuate thepower supply 814, which can transmit power to the temperature-control device 812. In other embodiments, a processor can actuate thepower supply 814. For example, in some embodiments, the system 800 (e.g., the electrical component 810) can include a temperature sensor. The temperature sensor can send signals to a processor, which can be positioned within theelectrical component 810 or elsewhere. The processor can determine, based on the signals from the temperature sensor, whether a temperature associated with theelectrical component 810 or thesystem 800 has surpassed a threshold. If the threshold has been surpassed, the processor can operate, for example via thepower supply 814, the temperature-control device 812. The temperature-control device 812 can heat or cool the shape-memory alloy actuatedfastener 806, which can cause the shape-memory alloy actuatedfastener 806 to change into another physical shape. This can decouple or couple theconductors - In some embodiments, the
system 800 can change temperature independent from the temperature-control device 812, for example, as a result of thermal energy from an electrical circuit or electrical circuit component (e.g., a processor). The changed temperature of thesystem 800 can cause the shape-memory alloy actuatedfastener 806 to change into another physical shape, for example, to its high-temperature shape. - In some embodiments, the high-temperature shape or low-temperature shape can include a physical shape in which a piece of the shape-memory alloy actuated fastener 806 (e.g., the clasps 808) can move, fold, bend, or expand. For example, the high-temperature shape can include a shape in which the
clasps 808 fold more than 90 degrees, as depicted by the arrows, such that theclasps 808 release their grip on theconductor 802. Further, in some embodiments, the shape-memory alloy actuatedfastener 806 can bend backwards (i.e., in the direction into the page), releasing theconductor 802 from theconductor 804. In some embodiments, this can sever the electrical connection between theconductors electrical components 810. - In one example, the
electrical component 810 coupled to theconductor 802 can include a power supply. Theelectrical component 810 coupled to theconductor 804 can include a computer. The shape-memory alloy actuatedfastener 806 can electrically couple theconductors fastener 806, the shape-memory alloy actuatedfastener 806 can change its physical shape, for example, to its high-temperature shape. This can decouple or release theconductors conductors system 800 can include an indicator (e.g., a LED or non-electronic indicator) to notify a user, for example, that the decoupling of theelectrical component 810 was intentional. Upon the temperature inside the computer cooling below the transition temperature of the shape-memory alloy actuatedfastener 806, the shape-memory alloy actuatedfastener 806 can change its physical shape, for example, to its low-temperature shape. This can couple or interlock theconductors -
