Ti-50%Ni (atomic fraction) alloy has the ability to restore the original shape under certain temperature conditions, so it is called titanium shape memory alloy.
NbTi alloy, when the temperature drops to close to zero, the conductor made of NbTi alloy will lose resistance, so that any large current will pass, the conductor will not heat up, and will not generate energy consumption, so NbTi alloy is called superconducting material.
Ti-50%Fe (atomic fraction) alloy has the ability to absorb a large amount of hydrogen. Using this feature of ferrotitanium alloy, hydrogen can be stored safely, that is, without using steel high-pressure cylinders to store hydrogen. Under certain conditions, the titanium-iron alloy can also release hydrogen, so it is called hydrogen storage material.
