Abstract

The cold swaging over the reduction of 90% is found to be effective to improve the final relative density to that for a bulk, sintered billet and to reduce the final grain size to be half. Due to the grain size reduction and high densification, the hardness of resintered Al₂O₃ billet becomes equal to or larger than that of bulk, dense Al₂O₃.
