Evaluation of Superalloys for Hypersonic Vehicle Honeycomb Heat Shields
Abstract
Foil gage superalloys are candidate materials for use in structural and heat shield panels for reentry and hypersonic vehicles. Unlike the coated refractory metals, little attention has been given to the potential environmental effects that may contribute to changes in mechanical properties of foil gage superalloys as a result of the low-pressure and slow-cyclic exposure of a typical hypersonic flight. The objective of this program was to investigate and evaluate operative degradation mechanisms so that reuse capabilities and limitations for promising nickel- and cobalt-base alloy foils (0.01 inch thick) could be predicted. The joining processes for the selected superalloys were selected and evaluated in a companion program.
