The report gives the current state-of-the-art of materials usage in aircraft gas turbine engines including auxiliary power units, and discusses the trends in future materials such as composites, powder metallurgy, controlled solidification, eutectic alloys, refractory metals, and ceramics. Also, discussed are new processing techniques such as thermomechanical processing (TMP) and Gatorizing, trade name. The appendix has 17 tables of materials used for components in such current production engines as the P+WA JT9D and the G.E. CF-6. The appendix also has a glossary of gas turbine engine terms.
