“…The A16061/WC/ Gr hybrid fabricated by Subramanya et al [7] through the stir-casting process by adding WC and Gr particles enhances the mechanical properties of AMMCs. Miranda et al [8] compared single reinforced composites such as AlSi/SiC and AlSi/Ti with hybrids such as AlSi/Ti/SiC and concluded that the latter have higher tensile strength. Baradeswaran et al [9] noted that the mechanical and wear properties of aluminium alloys, AA6061 and AA7075, were enhanced by adding 10 and 5 % by weight, respectively, of B 4 C and graphite by liquid casting.…”

The stir-casting method was employed to study the effect of adding silicon carbide and the bamboo leaf ash into the Al-4.5wt.%Cu alloy. The standard procedure was followed in analysing the mechanical behaviour of the fabricated composites on parameters such as density, tensile strength, and hardness. Optical microscope, scanning electron microscope with energy dispersive analysis of X-rays, and X-ray diffraction analysis helped in studying the microstructure of the composites. The study reveals that the reinforcement particles in the matrix alloy were distributed nearly homogeneously, and with a clear interface. The X-ray diffraction patterns indicate the presence of silicon carbide and bamboo leaf ash without an intermetallic reaction. The density of the hybrid composites reduces with the addition of bamboo leaf ash, but porosity increases. The fabricated composites gain in tensile strength and hardness as the reinforcement particles are added, but elongation was decreased.

“…The tensile strength of hybrid composite was found to be equal to 415 MPa, which was much higher than single reinforced aluminum composite. Miranda et al (2015) evaluated the tensile strength and wear rate of AlSi/Ti, AlSi/SiC and AlSi/Ti/SiC composite with gray cast iron counterface. It was found that tensile strength and wear resistance of hybrid composite was superior to single reinforced composite.…”

“…It was found that tensile strength and wear resistance of hybrid composite was superior to single reinforced composite. Miranda et al (2015) fabricated a SS316 alloy using selective laser melting and utilized the response surface methodology (RSM) for predicting the model and effect of process parameter through ANOVA. Davim (2000) concluded that thermal environment affects a smaller extent to wear rate and load affects a larger extent.…”

In this research work the dry sliding wear behavior of a hybrid aluminum metal matrix composite is evaluated. Al 6061 is used as a matrix material while Si3N4 and nano-graphite powder (3-15 wt.%) are used as reinforcements. These two reinforcements (50 wt.% of each) were blended in high energy ball mill for homogeneous mixing to get the sound aluminum matrix composite (AMC). The hybrid composite is made by stir casting route and its wear rate was investigated against an EN32 steel disc surface, using a pin-on-disc tribometer. Integrated Downloaded by [University of Cambridge] at 22:30 13 June 20162 response surface methodology (RSM) and genetic algorithm (GA) are used to optimize the pinon-disc process parameters. Analysis of variance (ANOVA) shows that sliding distance plays a major role on the dry sliding wear rate followed by load, sliding speed and reinforcements. Twofactor interactions and quadratic terms have also significant contributions. Genetic algorithm suggested a minimum wear rate value of 0.827 mg at optimized setting. Micro-structural analysis by scanning electron microscopy (SEM) reveals that very fine grooves are obtained at optimized settings while at other settings severe ploughing is observed. Transition of wear mechanism takes place with the increase of speed (i.e., temperature between the two rubbing surfaces) from abrasive to adhesive.

“…. [29] concluded that reinforced hybrid composites showed higher ultimate tensile strength and good ductility than [33] concluded that beyond certain limit of percentage of bamboo leaf ash in Al-MMC the ultimate tensile strength, hardness and percent elongation of the hybrid composites decreased. Aminullah, Eti Rohaeti, Irzaman [34] experimented using bamboo leaves ash which consists of silicon in it other than rice husk.…”

Manufacturing which involves material removal processes or material addition processes or material transformation processes. One or all the processes to obtain the final desired properties for a material with desired shape which meets the required precision and accuracy values for the expected service life of a material in working conditions. Researchers found the utility of aluminium to be the second largest after steel. Aluminium and its metal matrix composite possess wide applications in various applications in aerospace industry, automobile industry, Constructions and even in kitchen utensils. Hybrid Al-MMCconsist of two different materials, and one will be from organic origin along with the base material. In this paper an attempt is made to bring out the importance of utilization of aluminium and the challenges concerned in manufacturing and machining of hybrid aluminium MMC.
