Abstract

Templated grain growth is a promising processing route for the development of highly textured polycrystalline ceramics. The development of texture in ceramic materials has been an acknowledged, but poorly characterized, process. Several mechanisms have been invoked to explain texture development, including nucleation of oriented phases, anisotropic grain rotation, and the coarsening of favorably oriented grains. However, there has been little quantitative characterization of texture development to prove or disprove these mechanisms. As interest in texture development has increased, characterization techniques have been developed that have simplified the measurement and analysis of texture development. In this study, the microstructural evolution of liquid-phase-sintered alumina produced via TGG is measured in parallel with the texture development.
