3. Brief introduction of nitinol
Shape memory alloys also called SMA are made of more than two metallic elements with shape memory effect (SME) through thermoelasticity, martensitic transformation and its inversion. Shape memory alloy has the best shape memory performance among shape memory materials.
So far, more than 50 kinds of alloys have been found to have shape memory effects. There are many successful examples in the field of aerospace applications.
The huge antennas on satellites could be made of shape memory alloy. Before launching the satellite, the parabolic antenna is folded and placed inside the satellite. After the rocket lifts off to put the satellite into the orbit, it only needs to be heated. The folded satellite antenna has the function of "memory" and naturally unfolds to restore the shape of the paraboloid.
