HIGH TEMPERATURE MATERIALS DEVELOPMENT.

Abstract

Further investigation is made to increase the thermal shock resistance of zirconium Pyrocarbide. Test bars of the Pyrocarbide with excess PYROGRAPHITE continue to show exceptional flexural strengths at room temperature to 1500 C. Since, at the compositions under study, the continuous phase is that of graphite, the thermal and elastic properties of this material are similar to graphite. Calculated thermal shock resistance shows a hundredfold improvement over the stoichiometric compound. Shock test bars of these coatings are being forwarded to the Atlantic Research Corporation for evaluation. (Author)
