Shape Memory Alloys (SMA)

Shape memory alloys (SMA's) are metals, which exhibit two very unique properties, pseudo-elasticity, and the shape memory effect.

What is Pseudo-elasticity?
This is also called superelasticity. This is an elastic response in the materials in which, under mechanical stresses, it deforms to high strains (~10%) and when the stress is removed it gains the original shape.

What is Shape Memory Effect?
Shape-memory materials are stimuli-responsive materials. They have the capability of changing their shape upon application of an external stimulus. It is called the shape memory effect.

These materials are used for various engineering, high technology applications such as military, medical, safety and robotics.
