Abstract

Porous Fe-Al alloys with the nominal composition ranging from Fe-20 wt-%Al to Fe-60 wt-%Al have been fabricated by Fe and Al elemental powder reactive synthesis. The effects of the Al content on the pore properties of resultant porous Fe-Al alloys were systematically studied. It has been found that the volume expansion, the open porosity and the permeability can be manipulated by varying the Al content and that their maximum values are reached at Fe-45 wt-%Al. Their mechanical properties suggest that they are strong enough for the filtration applications.
