Abstract :

Fe72Al28 and Fe72Al26Sn2 alloys were milled for 24 hours, using vials and balls of stainless steel and a ball-to-powder weight ratio (BPR) of 16:1 in a planetary ball mill. The characterization of powders from each interval of milling was performed by X-ray diffraction, M�¶ssbauer spectroscopy, scanning and transmission electron microscopy. After 8 hours of milling formation of a nanocrystalline Fe(Al) solid solution occurs. Fe(Al, Sn) was formed after 12 hours of milling. The grain size decreases to 5 nm after 24 hours of milling. The Mossbauer spectra revealed that the FeAl and FeAlSn alloys formed during the low energy ball milling process contained different magnetic phases.
