The current work expects to decide the attributes of compression of the (Magnesium composite) AZ 91E-Zro2-Fly Ash Hybrid Metal Matrix utilizing the conventional explanatory strategy and limited component technique. Fly ash and ZrO2 taken as equal weight proportions, composites are fabricated by means of a vortex method under the path of stir casting. The density and fracture toughness were found experimentally, the experimental density was decreased compare to the theoretical density, but the density is increased slightly for composites compare to the base material. The fracture toughness is decreased for composites compare to the base material; this is due to the improvement of the grains by adding strengthening molecules. The compressive strength was decreased by decreasing of the height of the deformation in percentage for base material and the composites of H/D 1.0 and 1.5. The compressive strength is high for the composites compare to the base material even the density of the composite is little bit high, hence suggested that composite system gives the better compressive strength results

In this present research particulate reinforced aluminium metal matrix composites are developed by using sand mould and liquid stir casting processing route in which AA5052 reinforced with 5 wt. % SiC particulates of 63µm particle size. The density, porosity, micro-hardness, and compressive strength of SiC particulate reinforced AA5052 MMC were investigated and compared these properties with similar properties of unreinforced AA5052. The microstructure of the developed composite was also analysed by using optical microscopy, SEM, and XRD. Developed particulate reinforced Al metal matrix composite gives improved hardness and compressive strength as compared to the unreinforced AA5052. The addition of 5 wt. % SiC particulates increases the density of AA5052.

Purpose This study aims to attempt to make an aluminum-based composite using reinforcement such as graphite and fly ash. Pollution is an enhanced serious issue of concern for global. Industries play a major role in disturbing the balance of the environment system. Composite is made by using the stir casting technique. The waste that is generated by the industries if left untreated or left to be rotten at some place may prove fatal to invite various types of diseases. Proper treatment of these wastes is the need of the hour, the best way to get rid of such kinds of hazardous wastes is to use them by recycling. Design/methodology/approach Stir casting technique was used to make a composite. Graphite and fly ash were mixed with equal amounts of 2.5% to 15% in aluminum. The microstructure of composite formed after composite was noticed. After seeing the microstructure it was understood that reinforcement particles are very well-mixed in aluminum. Findings When graphite was mixed with 3.75% and 3.75% fly ash in aluminum, the strength of the composite came to about 171.12 MPa. As a result, the strength of the composite increased by about 16.10% with respect to the base material. In the same way, when 3.75% graphite and 3.75% fly ash were added to aluminum, the hardness of the composite increased by about 26.60%. Originality/value In this work, graphite and fly ash have been used to develop green metal matrix composite to support the green revolution as promoted/suggested by United Nations, thus reducing the environmental pollution. The addition of graphite and fly ash to aluminum reduced toughness. The thermal expansion of the composite has also been observed to know whether the composite made is worth using in higher temperatures.

Aluminium metal matrix composites are pretty much important in the different demanding sectors such as in the field of medicine and engineering like automobiles, aerospace, defence, dental and consumer goods. The need arises due to its huge calibre in industrial need of good materials with lighter weight, excellent properties and economical in cost demanded the researchers or scientists research on composite materials. The AMMCs or Al-MMCs consists of an apex variety of mechanical properties which is directly proportional to the chemical composition of the Aluminium matrix. To enhance strength the reinforcement plays a key role in AMMCs could be in the form of continuous/ discontinuous fibres, whiskers & particulate as the second phase depending on their applications and property requirements.

As auto manufacturers strive to meet imposed fuel economy and emissions regulations while producing vehicles with the quality and features that consumer expect, the industry needs to rely on advancements made in the field of metal matrix composites. The efforts of combining or replacing metals with the use of advanced metal matrix composites (MMCs) not only reduce weight, but can also improve safety, reliability and efficiency. A hybrid MMC was developed for the cylinder liner of advanced diesel engines. Composites of Al-6063 aluminium alloy reinforced with, fly ash particulate containing 10% and graphite particulate containing 5, 10 and 15 % were produced by stir casting. The wear and frictional properties of the casted hybrid metal matrix composites were investigated by performing dry sliding wear test using a pin-on-disc wear tester. The investigation was done to find the influence of applied load, sliding speed and sliding distance on wear rate, as well as the coefficient of friction during wearing process. From the investigation, it is evident that wear resistance of Al-6063 is increased while adding the fly ash and graphite reinforcement content. The results were compared with the existing liner material. From this comparative study the Al-6063/fly ash/graphite hybrid metal matrix composite can be the considered as an alternative material for existing cylinder material.
