摘要：
Porous FeAl alloy was prepared by Fe and Al elemental reaction synthesis. The cyclic oxidation evolutions of porous Fe-40 at.%Al alloy at the elevated temperatures of 600 and 800 A degrees C in air were studied and compared to porous materials of Ti, Ni, and 316L stainless steel. It has been shown that the oxidation of porous Fe-40 at.%Al alloy fitted a power law and no spallation was found after cyclic oxidation for 202 h in air. The porous FeAl alloy exhibits much better oxidation resistance than other porous materials, such as Ti, Ni, and 316L stainless steel, indicating that the porous Fe-40 at.%Al alloy has the highest structural stability at the elevated temperature in the oxidation atmosphere. Thus, the porous FeAl alloy can be used as filtering materials at elevated temperature in the oxidation atmosphere.
