Strength and Microstructure of Ceramics.
Abstract
Our goal in this program continues to be the understanding of the role of microstructure in the strength properties of ceramics. It is becoming increasingly apparent to the brittle fracture community that the toughness characteristics and flaw distributions of structural ceramics can be very much influenced, sometimes with great sensitivity, by small details in the microstructural makeup. For instance, the addition of less than 1% glassy phase to the grain boundaries of alumina polycrystals can alter the fracture properties dramatically, giving rise to significant improvements in strength.
