Gamma (K5 Based) Compressor Blade Material Design - Alpha Extrusion on a Small Scale

By: Nasa, National Aeronautics and Space Adm

The objective of the 2003 study is to develop a mechanically processed, high temperature TiAl alloy for use in the Turbine Based Combined Cycle compressor. An aging study with 3 temperatures and 4 time periods at each temperature will be conducted to determine the optimum aging condition. High-magnification microscopic analyses shall be employed to define the size distribution of carbide as a function of aging temperature/time. The contractor shall define optimum materials' conditions by conducting tensile and creep testing for two over-aging conditions for both alloys and fatigue testing for one over-aging condition for each alloy.Kim, Young-WonGlenn Research CenterTITANIUM ALLOYS; ALUMINUM ALLOYS; TURBINE BLADES; EXTRUDING; AGING (METALLURGY); MICROSTRUCTURE; HIGH TEMPERATURE; COMPRESSORS; MICROSCOPY; CARBIDES; SIZE DISTRIBUTION; TENSILE TESTS; CREEP TESTS; FATIGUE TESTS
