A shape memory alloy (SMA, also known as a smart alloy, memory metal, or muscle wire) is an alloy that "remembers" its shape. After a sample of SMA has been deformed from its original crystallographic configuration, it regains its original geometry by itself during heating (one-way effect) or, at higher ambient temperatures, simply during unloading (pseudo-elasticity or superelasticity). A single source on numerous aspects of intelligent materials Smart Materials focuses on many types of novel materials, including ceramics, hybrid composites, shape memory alloys, chitosan-based gels, adhesives, oxides, polymers, flip-chip technology, magnetorheological fluids, electrorheological materials, nanotubes, and sensors.5/5(1).

A series of Ti-rich Ni-Ti-Pt ternary alloys with 13 to 18 at. pct Pt were processed by vacuum arc melting and characterized for their transformation behavior to identify shape memory alloys (SMA) that undergo transformation between K and K ( °C and °C) and achieve recoverable strain exceeding 2 . Smart Materials focuses on many types of novel materials, including ceramics, hybrid composites, shape memory alloys, chitosan-based gels, adhesives, oxides, polymers, flip-chip technology, magnetorheological fluids, electrorheological materials, nanotubes, and sensors. It highlights the interdisciplinary nature of these materials by showing.

  Shape memory alloys are materials that are able to 'remember' their shape under different conditions. Here we show an example where the petals of the flower are made from a . Shape memory alloys. A group of metallic materials that can return to some previously defined shape or size when subjected to the appropriate thermal procedure. That is, shape memory alloys can be plastically deformed at some relatively low temperature and, upon exposure to some higher temperature, will return to their original shape.

Of results for Books: "Shape memory alloys" Design of Shape Memory Alloy (SMA) Actuators (SpringerBriefs in Applied Sciences and Technology) by Ashwin Rao, A. Srinivasa, et al. A shape-memory alloy is an alloy that can be deformed when cold but returns to its pre-deformed ("remembered") shape when heated.

It may also be called memory metal, memory alloy, smart metal, smart alloy, or muscle wire. [citation needed]Parts made of shape-memory alloys can be lightweight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based. 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 the behavior and utility of active or multifunctional materials and "smart" structures.5/5(1).

Shape Memory Alloy Engineering introduces materials, mechanical, and aerospace engineers to shape memory alloys (SMAs), providing a unique perspective that combines fundamental theory with new approaches to design and modeling of actual SMAs as compact and inexpensive actuators for use in aerospace and other applications.

With this book readers. Shape memory alloys are worth mentioning in this overview of actuator technologies because, despite a number of drawbacks, they are unmatched in work density and, as is not so well known, can be extremely high in power to mass [3, 4].These metal alloys undergo temperature driven phase transformation.

Temperature change is frequently achieved using a current pulse, particularly in nickel. Shape-memory polymers (SMPs) offer a number of potential technical advantages that surpass other shape-memory materials such as shape-memory metallic alloys and shape-memory ceramics.

This chapter presents a general overview of shape memory alloys (SMAs). A discussion about thermomechanical behaviors is carried out establishing the most important characteristics of these alloys.
