Super Waspaloy Microstructure and Properties

Source

Waspaloy is currently one of the more widely used alloys for turbine disk applications in the aerospace industry. However, higher engine performance demands by aircraft engine manufacturers have resulted in a number of approaches by material suppliers to upgrade the alloy. These approaches range from simple compositional modifications to a combination of chemistry modifications coupled with thermal mechanical processing. One such approach resulted in what is now commonly referred to as Super Waspaloy.

Tension, low-cycle fatigue, and creep rupture tests of Waspaloy and Super Waspaloy forgings were conducted from room temperature to 1089 K (1500°F), after which material properties were reviewed and correlated with the disk microstructure.
