Synthesis and Characterization of Fe2O3 Particulate Reinforced Aluminum Alloy: A Review

Aluminum alloy composite is the most widely used material because of its advantages over other composites. In this review, different methods of synthesis and characterization of Fe2O3 particulate reinforced aluminum alloy were discussed. It was observed that stir casting is the most commonly used process of synthesis over other processes. Large variation was found in RPM (CV = 0.39) of the stirring process but the time of stir was the same in all studies. It was also observed that characteristics of the composite were improved by the addition of Fe2O3 up to a certain limit. Very limited studies discussed the exact mixture proportion for optimum properties. The effect of the addition of pure Fe2O3 in the aluminum alloy is least studied.
