MOSSBAUER AND MAGNETIC STUDY OF MECHANICAL ALLOYING OF FE3SI

Using Mossbauer spectroscopy and measurement of hysteresis loops and t hermomagnetic curves, phase composition and magnetic parameters of Fe3 Si mechanically alloyed powders were studied in dependence on milling time and subsequent heat treatment at a thermomagnetic experiment. Sam ples of as-prepared powders show high value of coercivity, the saturat ion magnetization and the content of amorphous Fe3Si phase raise with increasing time of milling, the content of alpha-Fe diminishes. Heat t reatment of samples with long enough milling time can produce almost p erfect Fe3Si alloy.
