In this study, powder compacts produced by mixed elemental Fe, Mn, Al and C powders without ball milling were sintered at [Formula: see text]C and [Formula: see text]C, respectively. The results revealed that intermetallic phases belonging to Fe2Al5 and Al8Mn5 appeared after pre-sintered at [Formula: see text]C. When the temperature increased to [Formula: see text]C, only [Formula: see text]-Fe phase existed. The total porosities of the sintered samples were [Formula: see text] vol.% at [Formula: see text]C and [Formula: see text] vol.% at [Formula: see text]C, and the peak compressive strength of the [Formula: see text]C-sintered samples was [Formula: see text] MPa at the strain of [Formula: see text].
