Shape Memory Alloy - an overview | ScienceDirect Topics
Typically the shape memory alloy contracts at high temperature, and a tensile stress is needed to return it to its elongated state following cooling. A simplified version of the shape memory cycle is shown in Fig. 2.3. Mechanical elongation can be avoided when a two-way shape memory effect is induced .
A review of shape memory alloy research, applications and ...
Shape memory alloys (SMAs) belong to a class of shape memory materials (SMMs), which have the ability to ‘memorise’ or retain their previous form when subjected to certain stimulus such as thermomechanical or magnetic variations.
FLEXIBLE SOLUTIONS Get more MOVEMENT, SIMPLICITY and PERFORMANCE with less SIZE, WEIGHT and COST. For over 25 years DYNALLOY, Inc. has been manufacturing and creating state-of-the-art shape memory alloy actuator technology.

Nickel titanium, also known as Nitinol (part of shape memory alloy), is a metal alloy of nickel and titanium, where the two elements are present in roughly equal atomic percentages e.g. …History·
NASA turns to memory alloys for folding wings - New Atlas
NASA sees folding wings as a key aeronautical technology for the aircraft of tomorrow, and to make it practical, the space agency is looking to a cutting edge, lightweight memory alloy.[PDF]

“Parts made from shape memory alloys are typically 10 to 20 percent the size and weight of a conventional part,” says Jim Mabe, a shape memory alloy guru at Boeing.
Innovations: Shape Memory and Superelastic Alloys - Copper
Shape Memory and Superelastic Alloys Copper Applications in Innovative Technology. By Clive Barnes. Shape memory alloys (SMAs) are materials that can be deformed at one temperature but when heated or cooled, return to their original shape, i.e. the alloy appears to have a memory.
Shape Memory Alloy - Nitinol Shape Memory
Shape memory is a property of select materials that have the ability to "remember" the shape given during original thermo-mechanical processing allowing the material to revert to that original shape when subjected to heat.
Shape-memory alloys linear actuators: A new option for ...
In contrast, shape-memory alloy linear actuation can serve to make such installations function as proportional valves … because unlike solenoids, controls can drive the actuator to any position to control flow. Bundled-wire SMA linear actuators can also work as positioners (to compete against piezo technologies) in some cases.
NASA uses shape memory alloy to fold F-18 wing
The key to this is memory alloy, which is a special combination of metals that retains a "memory" of its shape. In other words, if you take a spring made of memory alloy, stretch it out of shape ...
Reinventing the Wheel
Oct 26, 2017· The game changing material that dramatically advanced the development of spring tires was nickel titanium, a shape memory alloy with amazing capabilities as explained by Santo Padula. After building the shape memory alloy tire, Glenn engineers sent it to JPL's Mars Life Test Facility.
The use of Shape Memory/Nitinol Alloys for actuation represents a technological opportunity for development of innovative thermostatic and electro-mechanical actuators: Shape Memory/Nitinol Alloy springs' or Nitinol trained wires' characteristic to ensure mechanical actions with temperature changes or heated with electrical current, allows the development of simple, more
Ultralow-fatigue shape memory alloy films | Science
Shape memory alloys can pop back into shape after being deformed. However, often these alloys cannot cope with a large number of deformation cycles. Chluba et al. find an alloy that avoids this pitfall, deforming 10 million times with very little fatigue (see the Perspective by James).Published in: Science · 2015Authors: Christoph Chluba · Wenwei Ge · Rodrigo Lima De Miranda · Julian Strobel · Lorenz Kie…Affiliation: University of Kiel · University of Maryland College Park
