Promoting Powder Metallurgy Technology Additive Manufacturing 4 positioning of AM vs. other pM technologies Additive manufacturing is complementing other powder metallurgy (PM) technologies. Like Hot Isostatic Pressing (HIP), AM is more suitable for the production of small or medium series of parts.
How metal powder is made is not necessarily simple, and there are only a handful of advanced powder metallurgy companies in North America. Don't worry -- the important concepts of the PM process aren't too difficult to understand with a proper explanation.

A program was conducted to develop nickel-base superalloy disk material using prealloyed powder metallurgy techniques. The program included fabrication of test specimens and subscale turbine disks from four different prealloyed powders (NASA-TRW-VIA, AF2-1DA, Mar-M-432 and MERL 80). Based on evaluation of these specimens and disks, two alloys (AF2-1DA and Mar …
