Mössbauer and magnetic study of mechanical alloying of Fe3Si

Using Mossbauer spectroscopy and measurement of hysteresis loops and thermomagnetic curves, phase composition and magnetic parameters of Fe3Si mechanically alloyed powders were studied in dependence on milling time and subsequent heat treatment at a thermomagnetic experiment. Samples of as-prepared powders show high value of coercivity, the saturation magnetization and the content of amorphous Fe3Si phase raise with increasing time of milling, the content of α-Fe diminishes. Heat treatment of samples with long enough milling time can produce almost perfect Fe3Si alloy.
