| 摘 要： | 研究了加入氧化铝对ZTM陶瓷结构和性能的影响.发现在烧结过程,氧化铝可固溶于莫来石颗粒形成富铝型柱状莫来石,并因其产生的体积膨胀增强了基质对氧化锆颗粒的约束,使材料中的四方氧化锆相对含量增加,其强韧化效果进一步发挥,明显改善了材料的力学性能.

| Abstract: | Effects of Al_2O_3 addition on the microstructure and mechanical properties of ZTM/Al_2O_3 composites were investigated. The formation of column_like mullite grains rich in alumina by Al_2O_3 incorporated in mullite during sintering process was found. The binding force of mullite upon ZrO_2 particle is enhanced and the amount of t-ZrO_2 in the specimens increases. Due to further developing of the transformation toughening, the mechanical properties are effectively improved. |
