英文摘要	The influence of Al(2)O(3)on the oxidation behavior of SiCf/(SiC + B4C) composite materials at 1200 degrees C in O-2/H2O (40/60) atmosphere was studied employing Scanning Electron Microscope, X-ray Diffraction and Material Universal Testing Machine. Results showed that Al2O3 could impede the crystallization of oxide (cristobalite) during cooling, and lead to a dense and smooth oxidized layer. Furthermore, the strength retention rate increases from 70.44 to 85.94% with Al2O3 after oxidization for 200 h. The above results are attributed to high viscosity and low reaction activity with steam of the aluminosilicates melt. Therefore, Al2O3 can significantly improve the oxidation resistance of SiCf/(SiC + B4C) composites in O-2/H2O atmosphere. (C) 2018 Elsevier B.V. All rights reserved.
