Thanks for the reply. We expect the anneal condition to be between 400C and 600C for several hours.

My concern is your anneal temperature. Ti can
oxidize extremely fast and the atmospheric tubes
will have a background of oxygen. I don't see a
problem with what you have proposed depending on
your anneal, which you have not outlined.
