oxygen,hydrogen,nitrogen in titanium
(OP)
I am working on a heat treat furnace and i need to know at what temperature rage does,Oxyegn,hydrogen and nitrogen start to get infused into the titanium?
We and the customer and I are not sure if we want to build and indirect fired or direct fired furnace. I have seen heat treating for titanium done both ways. Their is a large cost difference in the designs.
thanks,joe

RE: oxygen,hydrogen,nitrogen in titanium
What steps are done after heat treatment?
Do you care about surface damage?
What Ti alloys are you working with?
You can pull up thermodynamic data for this, but basically anything higher than about 200F and you will have detectable reactions with O, C, N, H, S and so on. The real question is what can you tolerate.
Unless these are large thick parts that will get extensive surface machining afterward I would never look at direct fired for Ti. Way too many risks.
