Abstract

The major hindrance in using structural ceramics in well defined engineering applications is their lack of reliability caused by uncontrolled flaw populations introduced during fabrication. Mechanical reliability is thus a matter of fabrication reliability. The strengthening that can be achieved by either eliminating or reducing the size of flaw populations through changing either processing or microstructure will be reviewed.
