Solid-state reactions during mechanical milling of Fe-Al under nitrogen atmosphere

Popis výsledku v původním jazyce

The sequence of solid-state reactions of iron and aluminum powders of approximate composition 82:18 in nitrogen atmosphere is followed during high energy ball milling. As an alternative, pieces prepared from Fe82Al18 ingot as the starting product are exposed to milling under nitrogen as well. X-ray diffraction, Mossbauer spectrometry, and electron microscopy supported by magnetic measurements have been applied to follow changes in the microstructure, phase composition and magnetic properties independence on milling time. The electron microscope observations show morphology of powder particles and changes in chemical composition during mechanical treatment. The changes in composition are observed at samples formed by mechanical alloying. On the other hand the composition of Fe82Al18 pieces is influenced by milling only weakly. The analysis of the room temperature X-ray diffraction patterns and of the Mossbauer spectra reflects an alloying process of elemental Fe and Al powders already a
