The nickel-titanium shape memory alloys exhibit common shape memory behavior and return to their original shape upon being heated to more than their phase transformation temperature. When heated to this temperature, the alloy transforms from its low-temperature monoclinic martensitic structure to the high-temperature cubic austenitic structure. @article{osti_, title = {Origin of the two-way memory effect in NiTi shape memory alloys}, author = {Manach, P Y and Favier, D}, abstractNote = {It is now well-known that the two-way memory effect (TWME) of shape memory alloys is obtained after a thermomechanical cycling called training.

actuator, biomedical application,clamping sys-tems,ect.). Shape Memory Alloys demostrate a unique ability to recover. 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.

Mechanical elongation can be avoided when a two-way shape memory effect. This book provides a working knowledge of the modeling and applications of shape memory alloys (SMAs) to practicing engineers and graduate and advanced undergraduate students with an interest in Shape Memory Effects in Alloys book behavior and utility of active or multifunctional materials and "smart" structures.

The book then describes various applications and design principles, for example in actuators, medical applications and as smart materials. The book contains chapters on shape memory ceramics and polymers as well as shape memory alloys, making the book a comprehensive account of the field.5/5(1).

The shape memory effect of the iron-platinum alloys is by no means inferior to that of the commercially available titanium-nickel and copper-based alloys, although the range of use is limited to low temperatures, as shown in Figure 1. Accordingly, the development of special applications for these alloys will be the subject of future investigations.

However, the complex relations between properties and structure have created a continuously growing interest for a deeper insight all this time.

The complexity of relationships between structure and properties is mostly related to the fact that strong?multidimensional. interactions are taking place: from Cited by: 9. The shape memory effect is a unique property of certain alloys.

Even though the alloy is deformed in the low temperature phase, it recovers its original shape on being heated to a critical higher temperature.

A shape-memory alloy is an alloy that can be deformed when cold but returns to its pre-deformed shape when heated. It may also be called memory metal, memory alloy, smart metal, smart alloy, or muscle wire.

Parts made of shape-memory alloys can be lightweight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based systems. They can also be.

The memory transfer temperature is the temperature that the memory metal or alloy changes back to the original shape that it was before deformation. This temperature can be very precise, within 1 or 2 degrees of the desired temperature. Training. Heating is the only way that most memory metals retain their original shape.
