When it cone to Waspaloy you probably want find very much information on forging as the people that can forge it keep there forging parameter very close to home. You can find a lot of articles where they compare forging IN718 and Waspaloy so you might look for links to additional papers.

I know we had a very hard time getting a turbine disc forged as it was a one off design and one off part.. We did order the second one before they forgot how they forged the first one.

I would check with Carpenter for information available to the public.

Cartech has two sources of good information. One is an article called "Forging Difficult Alloys" that is available from the following link:

Another is a booklet called "Forging Quality Stainless Steel & High Temperature Alloys". You can request that it be sent to you using the following link:

Here are a few references to the "Liquation Phenomena, cracking" that can occur in Waspaloy and other high Nickel Alloys, IE IN718, both during welding but also possible during forging.

Forging Waspaloy isn't for the faint of heart.
