Application of Rapidly Solidified Superalloys.

Abstract

This program is being conducted for the purpose of applying the principle of rapid solidation to superalloy powders and subsequent development of a stronger alloy composition for jet engine turbine airfoils. Centrifugal atomization and forced convective cooling are being used to produce the fast-cooled material. During this report period, heat treat studies to produce aligned grain structures, thermal stability evaluation, and initial mechanical property tests were run for 4 classes of experimental alloys. Results showed that 3 classes of alloys heat treated effectively and one of the alloys achieved levels of creep rupture strength commensurate with program goals. (Author)
