چکیده

Present paper reports an overview on the processing, corrosion behavior and applications of various metal matrix composites with a special focus on iron based metal matrix nanocomposites. As iron has a much higher melting temperature compared to aluminum, copper and magnesium therefore it is synthesized using powder metallurgy technique. P/M technique is widely used because it provides microstructural control of the phases with or without less excessive interactions between matrix and the reinforcement. Gupta et al. have reported that Fe-Al2O3 metal matrix nanocomposites show improved properties which include density, hardness, wear, deformation and corrosion respectively. This research work shows that due to reactive sintering an iron aluminate (FeAl2O4) phase is formed and hence various properties have been found to improve. It is anticipated that the results of these investigations will be useful in developing better technology for producing higher grade metal matrix nanocomposites.
