An experimental and analytical program was conducted to develop data for the screening and selection of alloys for use in APU system gas generator and turbine components, where such components are exposed to environmental effects of hydrazine decomposition products. Alloys selected for investigation were Haynes 188 and Inconel 600 as candidates for the gas generator, and Rene 41 and IN-100 as candidates for turbine components. Tension tests and compressive low-cycle fatigue tests were performed on hollow specimens pressurized internally with 700-psi NH3N2H2 gas mixtures simulating APU hydrazine decomposition products and with argon for comparison.
