Effect of Processing Parameters on the High Temperature Creep of SiC Whisker-Reinforced Alumina,

Abstract

This program investigated the role of processing on the high temperature creep behavior of polycrystalline alumina reinforced with SiC whiskers or particulates. Three types of tests were conducted. First, creep data were obtained on monolithic unreinforced alumina and on alumina composites reinforced with SiC whiskers or SiC particulates. Second, the effect of processing was investigated by testing conventionally processed composites and composites produced using a dispersion processing procedure. Third, the role of anelasticity was investigated by conducting stress removal experiments. A full description of the results of this program are contained in the publications documented in this report.
