Three special functions of titanium

(1) Shape memory function

This refers to the ability of a Ti-50% Ni (atomic) alloy to recover its original shape under certain temperature conditions, and it is called a shape memory alloy.
(2) Superconductivity
Refers to the NbTi alloy, when the temperature drops to near absolute zero, NbTi alloy made of wire, will lose resistance, any large current through the wire will not heat, no energy consumption, NbTi is known as superconducting materials.

(3) Hydrogen storage function
This refers to the Ti-50% Fe (atomic) alloy, which has the ability to absorb large amounts of hydrogen. Using this feature of TiFe, hydrogen can be safely stored, i.e., it is not necessary to use steel high-pressure cylinders to store hydrogen. Under certain conditions, TiFe can also be used to release hydrogen, and TiFe is known as an energy storage material.
