研究了两种杂质含量相同但性质不同的3Al2O3·2SiO2致密莫来石材料的力学性能。用SEM和TEM对材料的微观结构进行了表征。韧性、弯曲强度和杨氏模量已从室温至1400 °C测定。研究了韧性与应变速率的关系。特别注意的是，相关的力学参数的趋势，通过SEM断口观察。
The mechanical behaviour of two 3Al2O3· 2SiO2dense mullite materials with the same level of impurities but different in nature has been studied. Microstructure has been characterized by SEM and TEM. Toughness, bend strength and Young's modulus have been determined from room temperature up to 1400 °C. Dependence of toughness on strain rate has been investigated. Special attention has been paid to correlate the trend of the mechanical parameters to fractographic observations by SEM.
