Hydrogen as a Useful Alloying Element in Titanium Alloys

For many years hydrogen was considered as a deleterious impmrity which deteriorates mechanical properties of materials. This is clearly illustrated by hydrogen embrittlement of ferrous metals and alloys. The main effort of the research was aimed therefore at the study of hydrogen embrittlement and at the ways to avoid it.  

But numerous papers published during rece i decades showed that hydrogen can be a very useful alloying element for production of new materials (such as hydrogen accumulators, neutron absorbers, etc.) or new technologies for alloy processing with improved treatment parameters as well as with the improved final properties of the alloys.  

There are several reasons which made hydrogen processing most applicable to titanium alloys  

Titanium alloys are widely applied in aviation, rocket engineering and ship building due to their high strength, corrosion resistance and the small specific weight.
