Preparation and Phase Analysis of Fe-SiAlON-MoSi2 Composites

摘要：

　　Fe-SiAlON-MoSi2 composites were prepared using FeSi75,α-Al2O3,and MoSi2 powders as starting materials at 1400 ℃,1500 ℃,1600 ℃ and 1700 ℃,respectively,for 3h in a flowing nitrogen under the pressure of 0.9MPa.The results showed that the main phases of Fe-SiAlON-MoSi2 composite were β-SiAlON with deferent Z-values,MoSi2.and Fe3Si.Z-value of the obtained β-SiAlON depanded on α-Al2O3 content and the sintering temperature.The morphology of SiAlON phase changed from fibre-like of low Z-value to hexagonal prism-like of high Z-value.
