Where can I get information on heat treating tungsten?

[cpp01]

I need to find out some information on heat treating densamet (largely tungsten alloy) but cannot find any information from anywhere, so any information would be good!
Thank you,

I located a web site that lists various grades of Densamet alloys;

If this alloy is what I think it is, it is probably similar to Densalloy. We have used Densalloy for balance weights in low pressure steam turbines. The Densalloy is a sintered tungsten product using either iron-copper or iron-nickel as binders. The increased density of the alloy makes for great balance weight consolidation. However, the Densalloy will corrode in elevated steam temperature service (>700 deg F).

I don't believe this alloy is heat treatable after it is sintered. Someone else may have additional information.
