摘要：

Experiments were conducted on monolithic Al2O3 and Al2O3 composites reinforced with SiC-whiskers in which the load was removed during high-temperature creep. The monolithic material exhibited no anelastic recovery on load removal, but the composites showed a significant anelastic recovery which was reproducible and essentially independent of the total creep strain at which the load was removed. The results were consistent with the hypothesis that an interconnecting whisker network mav develop during processing of the composites.
