Abstract
The free energy of liquid phase of Fe-Si system using sub-regular Model was calculated. It was shown that the free enegy of mixture of pure elements was greater than that of an amorphous phase and the intermetallic FeSi compound. Thus it was estimated that an amorphous phase and the intermetallic compound could be produced by mechanical alloying. Mechanical alloying was carried out on the composition of Fe_(50)Si_(50). The alloying process was investigated by X-ray diffraction and differential scanning calorimetry(DSC). During mechanical alloying, the existence of an amorphous phase was not observed. However, the intermetallic FeSi compound phase was clearly observed.
