Abstract

To be able to satisfactorily bright-anneal metals having a high affinity to oxygen in a hood-type furnace or the like under a protective gas, a rather pure inert gas such as argon, neon or helium, which is mixed with not more than 50 vol-% of a reducing gas, for instance hydrogen, is used as protective gas in cooperation with an oxygen binder, preferably titanium.
