Ceramic Life Prediction Methodology.

Abstract

The objective of this program was to establish a method for predicting the lifetime reliability of structural ceramic materials in high temperature applications. Fast fracture and stress rupture data were collected on two materials, a sintered silicon nitride and a lithium-aluminum-silicate. The fast fracture data was presented graphically in the form of Weibull plots of percent failed versus failure stress. Stress rupture results were presented in tabular form. Photo micrographs were presented to illustrate the fracture surfaces of fast fracture and stress rupture failures. A program of specimen development was conducted. The objective of the program was to develop processing techniques to make it possible to fabricate integral shaft spin disks suitable for hot spin testing as stress rupture specimens. The hot spin disk stress rupture results were to be used to correlate experimental time dependent failure results with analytical time dependent failure results.
