摘要

The sintering behaviour of elemental powders of Fe and Al was investigated at various heating rates (0.5-10°C min^-1). It was found that the formation of porous FeAl material was accompanied by the volume expansion during the formation of the intermediate phase Fe₂Al₅. The final pore structure of porous FeAl material depends strongly on the heating rate; the higher the heating rate, the higher the volume expansion and the larger the porosity and the maximum pore size. It has been found that the pore structures produced with different heating rates experienced different formation routes.
