Three functions of titanium

Functional materials are engineering materials with physical properties, that is, materials that have special properties in electricity, magnetism, sound, light, heat, etc., or show special functions under their action.

The study of titanium and titanium alloys has found that it has three special functions and application prospects:

1. Memory function: Titanium-nickel alloy has unidirectional, bidirectional and all-round memory effect at a certain ambient temperature, and is recognized as the best memory alloy. In engineering to make pipe joints for the oil pressure system of fighter aircraft; The pipeline system of the oil complex; A 500mm diameter parabolic mesh antenna made of 0.5mm diameter wire is used on aerospace vehicles.

2. Superconducting function: niobium-titanium alloy shows zero resistance superconducting function when the temperature is below the critical temperature.

3. Hydrogen storage function: Titanium-iron alloy has the characteristics of hydrogen absorption, storing a large amount of hydrogen safely, and releasing hydrogen in a certain environment. It is very promising in hydrogen separation, hydrogen purification, hydrogen storage and transportation, and the manufacture of hydrogen heat pumps and batteries.
