| description.abstract | Amorphous and nanocrystalline phases generated in an elemental blend of
Al94.5Cr3Co1.5Ce1 composition (at.%) in the course of mechanical alloying (MA)
have been investigated by X-ray diffraction (XRD), transmission electron
microscopy (TEM), scanning electron microscopy (SEM) and differential
scanning calorimeter (DSC). It has been reported that rapid solidification
processing (RSP) of the same composition generates a finely mixed unique
structure consisting of nanoscale icosahedral (I) particles surrounded by a thin
Al phase [1]. In contrast, MA of Al94.5Cr3Co1.5Ce1 composition carried out in the
present study shows the formation of Al-based solid solutions along with partial
1
amorphisation. It emerges that during MA a wide difference in the atomic size
of the alloying elements in solid solution plays a pivotal role in the amorphous
phase formation. The possible causes of the difference in microstructure
generated by MA and RSP have been discussed. The thermal stability of the
mechanically alloyed product has also been investigated by a differential
scanning calorimeter (DSC) and XRD | en |
