Abstract EN
Densification behaviour of the powder particles in two- and/or multicomponent system is unpredictable.
The present work deals with the densification behaviour of Al-Fe powder particles during compaction and sintering in order to fabricate the Al-Fe metal matrix composites by powder metallurgy route.
Green compacts of Al-6.23 wt.% Fe powder particles were fabricated under varying compaction pressures, and these fabricated green compacts were sintered over a series of temperatures (430°C–590°C).
The sintered products have been characterised with the help of X-ray diffraction (XRD) and scanning electron microscope attached with energy dispersive spectroscopy (EDS).
It has been found that the green density of the compacts increases with increase in compaction pressure.
The rate of change in green density is found to be lower at higher compaction pressures.
Sintered density increases with increasing sintering temperature up to 550°C whereas a drop in sintered density is perceived at 590°C.
This decrease in sintered density is considered to occur due to swelling which has been explained on the basis of the Kirkendall effect.
The XRD and EDS analyses of sintered products indicated the presence of Al and Fe particles with the trace amount of intermetallics.
