Summary

A study is being conducted on the effects of environment on the mechanical behavior of transformation toughened ceramics for advanced heat engine applications. The primary goal of this program is to determine the effects of environment on toughening, strength, and crystal structure in commercially available transformation-toughened ceramics. Emphasis is focused on understanding the mechanisms responsible for environmentally induced strength degradation and crystal changes in the temperature range of 25° to 1050°C. The information and insight obtained from this program will be used to evaluate long-term applicability of toughened zirconia as diesel engine components.
