Transformation Toughened Ceramics. A Potential Material for Light Diesel Engine Application.

Abstract

This report contains three parts: The mechanical behavior of the composites in the system Al203:Cr203/Zr02:Hf02 are presented in the first part. The thermal conductivity studies of these compositions will be presented in the second part. The mullite - Zr02 system will be discussed in the third part. The results indicate that a composition containing 15 mole % of the Cr203 in the matrix phase has a thermal conductivity comparable to that of stabilized zirconia. Composites heat treated at 900 and 1200 C for 400 hours showed no degradation in mechanical properties. Originator supplied keywords include: Alumina; Zirconia; Toughened ceramics; Ceramics; Fracture toughness; Processing; Microstructure; Mullite.
