| abstract | ABSTRACT OF THE DISCLOSURE Novel transformation toughened ceramic compositions comprising finely divided ZrO2-HfO2 solid solution particles dispersed in a AL2O3-Cr2O3 (alumina) or 3Al2O3.2SiO2-3Cr2O3 .2SiO2 (mullite) solid solution matrix phase. It is found that increased hardness and modulus associated with higher relative Cr2O3 content (e.g. 20 mole %) in the matrix phase and increased fracture toughness associated with higher re-lative HfO2 content (e.g. 10 to 20 mole %) in the disperse phase represent viable and improved ceramic compositions. Such transformation toughened ceramic compositions are con-sidered useful in superhot light diesel engine applications, high temperature gas turbines and ultrahigh temperature ceramic heat exchangers. |
