Shape Memory Alloys. History. First discovered by Arne Olande in 1938. ?. He observed the shape and recovery ability of a gold-cadmium alloy (Au-. Cd). W.J. Buehler and Wang at the US. Naval Ordinance Laboratory. 1963. ? observed the shape memory effect in a nickel and titanium alloy, today known as nitinol (“Night
Shape Memory Alloys (SMA's) are novel materials which have the ability to return to a predetermined shape when heated. When an SMA is cold, or below its transformation temperature, it has a very low yield strength and can be deformed quite easily into any new shape--which it will retain. However, when the material is
A shape-memory alloy is an alloy that "remembers" its original shape and that when deformed returns to its pre-deformed shape when heated. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems. Shape-memory alloys have applications in

Introduction to Shape Memory Alloys. P. K. Kumar and D. C. Lagoudas. Shape Memory Alloys (SMAs) have been on the forefront of research for the last several decades. They have been used for a wide variety of applications in various fields. This chapter introduces the unique behavior that is observed in. SMAs.
shape are of commercial interest. To date, this has been the nickel-titanium alloys and copper-base alloys such as Cu-Zn-Al and Cu-AI-Ni. A shape memory alloy may be further defined as one that yields a thermoelastic martensite. In this case, the alloy undergoes a martensitic transformation of a type that allows the alloy to

SHAPE MEMORY ALLOYS. A shape memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that "remembers" its original, cold-forged shape: returning the pre- deformed shape by heating. This material is a lightweight, solid-state alternative to conventional actuators such as
