Advances of Abnormal Grain Growth to Toughen A12O3 Ceramics
异向生长晶粒增韧氧化铝陶瓷的研究进展

This paper presented the characterization of microstructure of A12O3 with abnormal grain growth (AGG). The effect of different additives, seeds and introduction of seeds on AGG, microstructure and mechanical property of A12O3 was summarized systematically. The mechanism of AGG under different conditions was discussed. Also, the mechanism to toughen A12O3 ceramics with AGG was interpreted preliminarily.
