Abstract
Porous FeAl material has been prepared by reactive synthesis and the pore structure have been characterized. The results show that swelling is the main behavior during reactive synthesis process. When the sintering temperature is below 1000°C, the open porosity and maximum pore size of porous FeAl material increase with the increasing of sintering temperature. After sintered at 1000°C, the porous FeAl material has the porosity of 35.3%, maximum pore size of 2.0μm. The main pore formation mechanisms were the Kirkendall effect, reaction and the evolvement of interparticle pores.
