Abstract

Abstract In situ co-textured microstructure of alumina/alumina:Ca-hexaluminate multilayer composites has been investigated. Ca-hexaluminates, in situ grown in the presence of CaMgSiO 4 glass, showed a well-textured microstructure in Ca-hexaluminate/alumina multilayer composites. In situ texturing of Ca-hexaluminate was possible through the microstructure texturing of alumina using alumina platelets and CaMgSiO 4 glass. CaMgSiO 4 glass addition was effective for the in situ texturing of Ca-hexaluminates as well as the microstructure texturing of alumina. The in situ textured Ca-hexaluminate and alumina multilayer composites provide a well-controlled crack propagation because of crack shielding and crack deflection.
