Three functions of titanium

Functional materials are engineering materials based on physical properties, that is, materials with special properties in electricity, magnetism, sound, light, heat and other aspects, or show special functions under the action of them.

Studies on titanium and titanium alloys have found that they have three special functions which are promising for application :

1. Memory function: Ti-Ni alloy has unidirectional, bidirectional and omnidirectional memory effects at certain ambient temperature, and is recognized as the best memory alloy.

In engineering to do pipe joint for fighter oil pressure system;

Pipeline system of petroleum complex;

A 500mm diameter parabolic mesh antenna made of 0.5mm diameter wire is used on the space vehicle;

Used in medical engineering to make treatment for snoring;

Made of screws for fracture healing.

The above applications have obtained obvious effects.

2. superconducting function: niobium - titanium alloy at the temperature below the critical temperature, presents a zero resistance superconducting function.

3.hydrogen storage function: titanium - iron alloy has the characteristics of hydrogen absorption, a large number of hydrogen safely stored, in a certain environment and hydrogen released.

It is very promising in hydrogen separation, hydrogen purification, hydrogen storage and transportation, manufacture of heat pumps and batteries using hydrogen as energy.
