Abstract

Iron aluminum alloy with composition of 30, 35 and 40 at % Al were prepared via powder metallurgy route: mechanical milling, consolidating, sintering. Solid solution Fe (Al) formed after several hours milling, and completely at around 10h from elemental powders. During sintering, phase transformation take place from solid solution Fe(Al) into intermetallic FeAl and carbon impurities from elemental powder lead to an in situ precipitation of κ-AlFe3C0.5 simultaneously. Mechanical properties were improving with higher Fe contents and higher sintering temperature with maximum hardness of 5.5 GPa and maximum yield stress of compression test of 700 MPa in the sample of 30 at %Al, 1 h sintering of 1300°C after 10 h milling. The mechanical properties of sintered samples will be discussed in term of microstructure, precipitate and phase formed after sintering.
