This volume describes a materials investigation that was conducted to select, test-evaluate, and further develop materials that would be suitable for fabrication of high-temperature turbine components. The initial activities consisted of studies to determine the most desirable intermetallic composition for high-temperature 2400F range uncooled turbine components. These activities resulted in the development of a beryllide intermetallic composition, identified as Composition 1. Specimen-type testing was then conducted to evaluate the mechanical and physical properties of Composition 1 and those of high- temperature alloys, IN-100 and AiResist 13. Parallel activities were then conducted, which consisted of a cascade rig testing of Composition 1 and b intermetallic composition studies under to improve the low-temperature ductility and high-temperature stress-rupture strength characteristics of Composition 1.
