Abstract
Ceramic and ceramal materials have been investigated for use as turbine-blade materials for aircraft gas turbines. Tensile, flexure, thermal-shock, and oxidation data for these materials at temperatures up to 2400 F are presented. These data are discussed with respect to applicability for turbine use. Results of turbine-blade operation at the NACA Cleveland laboratory are given.
