Abstract Porous Fe-25 wt.% Al alloy is synthesized by reactive synthesis with Fe and Al powders as the raw materials. Various processing parameters such as the final sintering temperature, pressure during cold pressing, and powder size are investigated to control the pore structure of the alloy. It has been shown that the optimal final sintering temperature is around 950-1050 degrees C. When the pressure is higher than 110 MPa, the variation of the pore structure is mainly caused by the change of the pore nature in the as-pressed compact. In addition, the pore structure of porous Fe-25 wt.% Al alloys depends on the size of the raw powders and the weight fraction of different-sized raw powders. ©2010 Springer Science+Business Media, Inc.
