“…It was found that MgO possesses better mechanical property than the other reinforcements. A lot of researchers had 9 concentrated on developing new composites such as Al 6061, LM25 reinforcing with various elements such as TiB 2 , SiC, TiC, ZrB 2 , AIN, Si 3 N 4 , Al 2 O 3 and their mechanical properties were analyzed by earlier researchers [6][7][8][9][10][11][12][13][14][15][16]. Very few works were identified in analyzing the effect of MgO on hardness analysis.…”

Aluminium based composite materials (LM25 alloy) was fabricated by stir casting method at different percentages like 3%, 6%, 9% and 12% weight percentage of MgO. The four samples were prepared by using the above method. Then the four samples are heated at different temperatures such as 200ºC, 300ºC, and 400ºC in the muffle furnace. Then the heated specimens are cooled to room temperature by air cooling method. The four samples are subjected to Rockwell Hardness tester at four different elevated temperatures. The hardness of the specimen was investigated by the reinforcement of MgO. The maximum hardness was obtained at 12% of MgO. Similarly, the temperature was increased. Correspondingly the hardness of the specimen was also increased. The maximum hardness was obtained at 400ºC. The microstructure of the above mentioned four samples was evaluated by using scanning electron microscopy. The EDAX test revealed that Fe, Cu, Mg, Al, and Si, are present in the composite specimen. The EDAX test confirmed that the above metal matrix composite is aluminium based composite.
