Abstract
Mechanical alloying in the Fe(1-x)Bx system was performed by ball-Milling. The Mechanically alloyed powders were investigated by X-ray diffraction, differential scanning calorimetry (DSC), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM). In case of Fe(1-x)Bx (x=0.2) specimen, the broad peak of x-ray diffraction and the exothermic peak of DSC indicated the characteristic behavior of amorphous alloy. However, TEM observation revealed the existence of fine bcc Fe phase. On the other hand, the boride of Fe₂B or FeB was formed by mechanical alloying in Fe(1-x) Bx (x＞0.3) specimens.
