Abstract
Mechanical alloying (MA) for Fe-C-Si mixtures of elemental powders was performed by a conventional ball-mill under an argon gas atmosphere. The phase formation on the ball-milling process was studied by X-ray diffractometry and differential scanning calorimetry.
An addition of silicon suppressed the formation of iron-carbides to promote the amorphization. For high silicon concentration, intermetallic compounds such as FeSi, β-FeSi2 and SiC were formed after indicating the partial amorphous formation. The inhomogeneous reaction, the slow reaction, which is a characteristic in MA of metal-nonmetal systems, was confirmed for Fe-C-Si system.
