In order to determine the
amorphization time, Fe and Al elemental powder mixtures with composition of Fe10.8Al89.2, Fe50Al50 and Fe80Al20 were mechanically
alloyed in a Spex 8000D Mixer/Mill for up to 96 h. The characterization of
Fe-Al powder mixtures was studied as a function of mechanical alloying time by
X-ray diffractometry and scanning electron microscopy. A fully amorphous phase
was not observed by X-ray diffraction for Fe10.8Al89.2 and Fe80Al20 even after
96 h mechanical alloying. However, X-ray diffraction observation showed that 50
h mechanical alloying of Fe50Al50 alloy resulted in a fully amorphous phase formation.
