چکیده انگلیسی
The aim of this work was to investigate the kinetics of structural transformations during mechanical high energy ball-milling of Fe2O3 with Ga in order to reveal the mechanism of the process. The structure of formed intermetallic phases and intermediate oxide compounds were studied by means of Mossbauer spectroscopy, IR spectroscopy and X-ray diffraction. After 8Â min of attrition a large part of Fe2O3 still remains in mixture. This fact could be explained in view of melted Ga spreading over freshly prepared surfaces during milling process and incorporating into the Fe2O3 and intermediate oxides structures.
