Title: Toughened ceramics life prediction. Final technical report

Abstract

The objective of this research was to understand the room temperature and high temperature behavior of brittle materials such as in situ toughened ceramics, glasses and intermetallics as the basis for developing life prediction and test methodologies. A major objective was to understand the relationship between microstructure and mechanical behavior within the bounds of a limited number of materials. A second major objective was to determine the behavior as a function of time and temperature. Specifically, the room temperature and elevated strength and reliability, the fracture toughness, slow crack growth and the creep behavior. These results will provide input for parallel materials development and design methodology programs. Resultant design codes will be verified. A summary of the accomplishments that occurred under this program is given.
