摘要：

Al2O3 nanobelts were observed in the material Al2O3/SiC mu/SiCn nanocomposite with high-resolution transmission electron microscopy (HRTEM), the forming of ductile nanobelts is helpful for the improvement of fracture toughness. In addition, the special microstructure such as dislocations and compound twins were also observed in the nanocomposite with TEM, the complicated dislocation configurations and the forming of twins in larger SiC particles contributed to the improvement of fracture toughness by dissipating fracture energy. The Al2O3/SiC interface bonding was strengthened which also lead to the high mechanical properties of the nanocomposite. (c) 2007 Elsevier B.V. All rights reserved.
