Description
In this work, the obtaining of amorphized ferromagnetic particles by
mechanical milling has been studied. For this purpose, the compositions Fe₇₈Si₂₂
and Fe₇₈Si₉B₁₃ have been studied and the results have been compared in order to
determine the best characteristics achieved with this technique. The behavior has
been studied when other elements are introduced to iron, which is the main base
material for the manufacture of magnetic cores, the target of these amorphized particles. This mechanical alloying technique is an ideal alternative technique to the
conventional obtaining of these particles due to the particular way in which amorphization is achieved by extremely severe deformation of the structure. A study
encompassing different alloying conditions, for each of the compositions studied,
has been carried out and measured by X-ray diffraction, SEM and TEM techniques
and granulometry to compare their morphology and different characteristics. The
milling hours studied vary from 60 to 200 h of alloying, dry, resulting in the best
nanocrystalline-amorphous characteristics at around 100 h of milling. The alloy of
composition Fe₇₈Si₉B₁₃, which is one of the Metglas compositions, turns out to
have the best characteristics, reaching a high amorphous-nanocrystalline character.
