摘 要：Porous Fe-Sialloys with different nominalcompositions ranging from Fe-10wt% Sito Fe-50wt% Siwere fabricated through a reactive synthesis of Fe and Sielementalpowder mixtures.The effects of Sicontents on the pore structure of porous Fe-Sialloy were investigated in detail.The results showed that the open porosity,gas permeability and maximum pore size of the porous Fe-Sialloys increased with increasing Sicontents,indicating that the porosity and pore size can be tailored by changing the Sicontents.The pore structure parameter including the open porosity,gas permeability,maximum pore size obeyed the HagenPoiseuille formula with the constant G=0.035 m(-1Pa-1s-1 for the reactively synthesized porous Fe-Sialloys.The mechanicalproperty of the porous Fe-Sialloys showed applicability in the filtration industries.
