final correction...RE: processing of Ti foil in SNF?

[Ed Myers]

Robert,

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.

Regards,
Ed
