Metal matrix composites (MMCs) possess significantly improved properties compared to unreinforced alloys. There has been an increasing interest in composites containing low density and low cost reinforcements. In view of the generation of large quantities of solid waste by products like fly ash and slags, the present study is discarded, new methods for treating and using these solid wastes are required. Hence, composites with fly ash and Granulated blast furnace slag as reinforcements are likely to overcome the cost barrier for wide spread applications in automotive and small engine applications. In the present investigation, AA 2024 alloy – 5 wt. % fly ash and slag composites separately were made by stir casting route. Phase identification and structural characterization were carried out on fly ash and GBF slag by X-ray diffraction studies.The hardness and compression tests were carried out on all these alloy and composites. The reinforcement Improved hardness and mechanical properties were observed for both the composites compared to alloy; this increase is higher for AA2024-Fly ash composite than AA2024- Granulated blast furnace slag composite.
