Abstract
Bicrystals of alumina containing a glassy phase were produced by hot-pressi ng. Annealing the bicrystals at high temperatures (where a liquid forms at the boundary) can result in migration of the grain boundary. The migration of the boundary proceeds by the solution/reprecipitation mechanism. Many of the features of the migration closely resemble diffusion-induced grain-bou ndary migration but some important differences are identified. (C) 2001 Act a Materialia Inc.
