Applied High Temperature Technology Program. Volume I.
Abstract
The initial effort consisted of the development of aircooled columbium and thoria dispersed (TD) cobalt vanes for installation in an advanced development engine. The redirected effort, covered in the report, continued this development by further characterizing the poor fatigue behavior of the coated SU-31 columbium alloy and substituting a directionally solidified eutectic alloy for the TD cobalt material. The gamma/gamma'+delta D.S. eutectic alloy was chosen for this program. A technology base for design of gamma/gamma'+delta D.S. eutectic hardware is presented. This includes: casting, coating, joining, hole drilling, and material property evaluation. Material laboratory tests are described and data presented. Applications to aircooled turbine hardware is discussed.
