I memory alloy is a metal that remembers its cold forged which basically shaping the material into a shape without heating it. They have to cold forge it because when they heat it changes the working hardness area of the metals eternal structure part of the structure e.g. a Corner and this how the memory alloy works. An example of a copper aluminium nickel sam skellern
Shape Memory Alloys are materials which have the ability to return to their original shape when heated. When one of these is cold, it can be deformed really easily. However when it is heated it undergoes a change in crystal structure and it changes the shape of the material.
Materials that have shape memory alloys are:
Nickel. Titanium.
These materials have good electrical and mechanical properties and high corrosion resistance.
Products that are Shape-Memory Alloys: Boeing use these for their Aircraft engines to reduce noise. They are sometimes applied in medicine. Dental Braces use Shape Memory Alloy technology.
Shape Memory Alloys (SMAs) are materials that can return to their original shape once heated above a certain temperature. SMAs have two stable phases High-Temperature phase (also called Austenite) and low-temperature (also called Martensile). Once a shape memory alloy has been heated above its transforming temperature the material will have one crystal structure which it will form to and once the material is below its transforming temperature the material can be shaped and permanently deformed. Then once it is heated the material will return to its original shape. Some types of shape memory alloys: Nickel-titanium Gold-cadmium
You can also get different types of shape memory alloys, for example magnetic shape memory alloys (MSMAs) and electric shape memory alloys (ESMAs). MSMAs change their shape when an external magnetic shield has changed causing the material to change. Also ESMAs change their shape when the current of electricity has changed or allowed to flow through the material.
