“…For instance, turbine blades of high strength are manufactured at a low cost using this technique. Using this technique, fabrication of glass fiber reinforced fly ash composites with (0, 5,10, and 15 wt.%) reinforcements has been reported [6]. In addition, fabrication of Eglass/epoxy-based composite slabs has been reported with Al2O3, magnesium hydroxide, hematite powder [19].…”

“…The former is used in the preparation of ultra-light composites due to their low density when compared to the density of metal matrix whereas, the latter is used for the enhancement of properties which include density, wear resistance, stiffness and strength [10], [11]. Fly ash is a major industrial waste from thermal power plants and is highly abundant in nature owing to its low cost coupled with low density [6], [12]- [14]. Table.…”

The present decade has witnessed numerous investigations focussed on the determination of the mechanical properties of Fly ash composites. These composites have attracted attention, especially in the form of reinforcements owing to their excellent tensile and compressive properties coupled with impact and hardness response. A number of techniques viz. in-situ deposition, hand-up lay and compo-casting techniques have been reported to fabricate these composites. However, in the context of these composites, a systematic structure-property correlation has not been established till date. The present review is aimed at highlighting the current state of research in the avenue of Fly ash composites from two different viewpoints, viz. (i) fabrication technique and (ii) mechanical properties of the fabricated composites. Moreover, the necessity of establishing systematic structure-property correlation in these materials has also been briefly discussed from the author’s viewpoint.

“…One advantage of metal matrix composites is the ability to modify the thermal properties, such as thermal conductivity and coefficient of thermal expansion through the proper control of reinforcement and matrix. In addition, the manufacturing flexibility of the metal matrix composite by various processes allows the fabrication of complicated shaped parts [3,4]. Aluminium metal matrix composites are desired engineering material for aerospace, automobile and mineral processing industries for various high performing components that are being used for varieties of applications [5]; owing to their lower weight and excellent thermal conductivity properties [6].…”

In the present study, the thermal behavior of pure Al6061 and fly ash reinforced Al6061 with varying particulate sizes were investigated for the first time. Metal matrix syntactic foams of ceramic fly ash (4 – 16 wt. %) embedded in aluminum (Al6061) matrix have been fabricated by using stir casting technique with different fly ash particulate sizes of size below 50µm and 53µm-100µm, respectively. The microstructural characteristics were studied by using scanning electron microscopy (SEM). It has been observed that there is a uniform distribution of lower particulate size fly ash as compared to higher particulate size in the aluminium matrix respectively. For all the cases, the accumulation of fly ash in Al6061 decreases the thermal conductivity and increases the specific heat carrying capacity of a hybrid composite. Increase in weight percentage of fly ash in Al6061 decreases thermal conductivity and thermal diffusivity respectively.

“…The effect of reinforcements and machining parameters such as cutting speed, feed rate, and depth of cut on surface roughness, which greatly influence the performance of the machined product, were analyzed during turning operation. Rao et al, (2014) investigated the machining behavior of Al6061-flyash composite in Jobber XL CNC by using M2 grade HSS and K10 grade carbide inserts as cutting tools. The investigated result conclude that the increased fly ash content in the composites of Al6061 reduces the premature failure of the cutting tool by reducing built up edge formation.…”

Turning experiments were conducted on a novel aluminum alloy (LM6)/fly ash composite based on the response surface and face centered central composite design methodology. The effects of cutting parameters on surface roughness and tool wear were investigated. Multiple regression models were developed for the responses and the adequacies of the developed models were tested at 95% confidence interval using the analysis of variance (ANOVA) technique. Carbide inserts (Model: CNMG 120408-M5) were used for turning the specimens in a CNC turning machine (model: LT-16). The test for significance of the regression models, the test for significance on individual model coefficients and the lack-of-fit tests were performed using the statistical Design-Expert7.0v software environments. R2 indicated the model significance and the value was more than 97%, revealed that the relation between cutting responses and input parameters held good for more than 97% and the model was adequate.
