Composites are most promising materials of recent interest. 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 expensive manner in which it is discarded, new methods for treating and using these solid wastes are required. Hence, composites with fly ash and granulated blast furnace (GBF) 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 GBF 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. Scanning electron microscopy with energy dispersive X-ray spectroscopy EDS was used for microstructure analysis. The hardness and compression tests were carried out on all these alloy and composites. The SEM studies reveal that there was a uniform distribution of fly ash and GBF slag particles in the matrix phase and also very good bonding existed between the matrix and reinforcement. Improved hardness and mechanical properties were observed for both the composites compared to alloy; this increase is higher for Al-fly ash composite than Al-GBF slag composite.

“…Hydraulic mounts are an excellent compromise, as they can adjust to a firm or soft setting depending on driving conditions, but they add complexity, cost and weight. Fly ash reinforced aluminium shows promise as an alternative to commonly used mount materials, as the syntactic metal foam has superior dampening characteristics, is lighter than solid aluminium and is less expensive to produce because less aluminium is used [24].…”

“…When properly used in a structural application, this property allows undesirable noise and vibration to be passively attenuated and removed to the surroundings as heat. 9) To measure the vibration damping capacity, the specimen with dimensions of 1:0 Â 10 Â 120 mm (thickness Â width Â length) was machined using wire electrical discharge machining (EDM), followed by austempering and then subzero treatment. The damping capacity was measured with a flexural internal friction measurement machine (IFT-1500; ULVAC Inc., Japan) at room temperature.…”

We investigated the effects of austempering and subzero treatment on the damping capacity in austempered ductile cast iron. The damping capacity of austempered ductile cast iron was rapidly increased by the austempering treatment, although it was not affected by the austempering temperature or time. After subjecting the austempered ductile cast iron to subzero treatment, the austenite was transformed into martensite, and the volume fraction of the martensite increased as the subzero treatment temperature decreased. The subzero treatment sharply increased the damping capacity of the austempered ductile cast iron. However, the damping capacity gradually increased as the subzero treatment temperature decreased. By increasing the subzero treatment time, the damping capacity rapidly increased until the subzero treatment time reached 30 min, after which it increased gradually. By increasing the volume fraction of the martensite, the damping capacity was rapidly increased until the volume fraction was 5%, beyond which it increased gradually.
