Improving titanium-zirconium-molybdenum performance

Titanium zirconium molybdenum (TZM) has many good performances, and it is often used as high temperature structural components. However, it also has some drawbacks that it be limited in application. And improve the performance of titanium zirconium molybdenum methods have two which are to improve its oxidation resistance and the using neutron irradiation method.
Firstly, TZM oxidation resistance is not very good, it can not generate anti-oxidation layer to protect itself, and it will limit the range of applications and service life. Improve TZM antioxidant properties there are two main methods. The first is alloyed, which is adding trace elements in the alloy to improve oxidation resistance of the TZM, but this method of alloying at a high temperature oxidation is not strong resistance. The second method is coating surface technique in which coated a protective layer in the surface of the alloy. And the pack cementation method because it has a low cost, easy to control, substrate and coating adhesion is widely used.
On the other hand, after further research found that using neutron radiation method can change TZM ductile-brittle transition temperature and mechanical properties, thereby improving the performance of TZM.
