Can anyone please direct me to some sources of information on particle/powder metallurgy production processes?

Technical information is required - I'm trying to find some but keep running into press releases and general public-level information which isn't useful for my purposes.

Book recommendations are okay but of course I'd prefer free, online, and good if such a combination exists.

Thank you all in advance for your help!
 
Nevermind all, I answered my own question. In case you're curious...

"Corrosion resistant, high vanadium, powder metallurgy tool steel articles with improved metal to metal wear resistance and a method for producing the same"
US Patent # 5,679,908
Assignee: Crucible Materials Corporation
 
Here's another one for the curious (probably more applicable to knives than the previously mentioned patent, which is specifically for metal-to-metal applications):

Wear resistant, powder metallurgy cold work tool steel articles having high impact toughness and a method for producing the same
US Patent # 5,830,287
Assignee: Crucible Materials Corporation

and also

High strength martensitic stainless steel alloys, methods of forming the same, and articles formed therefrom
US Patent # 7,901,519
Assignee: ATI Properties, Inc.

The latter I found after doing a search on the USPTO Patent Database for "Carpenter Technology Corporation" and is awesomely detailed, which is expected given how unambiguous a patent application must be in order to be granted protection rights.

Thanks for the lead hardheart, and cheers to all the geeks out there who might actually read this stuff.
