Smart alloys are alloys that had unusual properties
-after being bent down, it returns to it's original shape afer heat or an electric current passed through.
One way memory effect: when the metal is in it's cold state, it can be bent. Upon heating, it will turn into it's original shape again.
Two way memory effect: the metal can turn back to both shapes in high temperature and low temperature, unlike one way memory effect which can only remember it's high temperature's shape
Eg -NItinol (alloy of nickel and titanium)
- Copper-aluminium-nickel
Application: industrial: air craft, piping
medical use: Orthopedic surgery, dentistry
robotic
