Abstract
The VADER process is a new melting and casting technology which has potential as an alternative for P/M superalloy processing. The process yields a uniformly fine grain, high strength superalloy structure which:
-
is free of deleterious macrosegregation,
-
can be ultrasonically inspected, and
-
can be forged into desired components.
The equipment and the process are described and contrasted to conventional superalloy melting and casting technology. The science, engineering, and economic advantages are cited. Detailed macrostructures and microstructures of example VADER processed alloys, Udimet 718 and Udimet 700, are presented. The current status and a look into the future are highlighted. The current status and a look into the future are highlighted.
