“…33 that is higher stirring speed at higher level of wt% marginally affects the amount of porosity present in composite. Since the optimum parameter used in this experimental study controls the excess porosity percentage in the fabricated composites as it results in local clustering, voids and agglomeration on overall surface of composites, which furthermore suppresses the mechanical properties of composites, 37,38 yet its lower value was found in this study due to the following reasons. The use of ultra-pure argon gas as deoxidizing agent to prevent the molten fluid from atmospheric contaminations. Preheating the reinforcements before melting and pouring. The addition of Mg into the molten matrix ensured uniform wettability. Using vacuum environment during poring to minimize air bubbles and gas blister.…”

This experimental analysis aimed to fabricate low cost, lightweight metal matrix composite using Al 6061 as matrix material and alumina (Al2O3) and bagasse ash as reinforcing material through stir casting process. In this process one cast of single reinforced composite (Al 6061/5 wt% Al2O3) and three casts of hybrid reinforced composite (Al 6061/5 wt% Al2O3/ 4, 6, 8 wt% bagasse ash) were developed and processed as per ASTM standards followed by mechanical (micro-hardness, ductility, compression, tensile, and impact strength), physical (density and porosity), and microstructure (optical and SEM microscopy) characterization. The mechanical properties such as tensile strength, hardness, and compressive strength showed good improvements in the manufactured hybrid reinforced metal matrix composite (HRMMC) in comparison with the single reinforced metal matrix composite (SRMMC). The tensile strength and hardness of developed composite increased continuously with an increase in bagasse ash contents up to 6 wt% having maximum increment of 9.09% (tensile) and 16.5% (hardness) and thereafter both decreased for 8 wt% of bagasse ash, respectively. The results of impact strength and ductility of Al 6061/Al2O3/bagasse ash showed marginal reduction, as the wt% of reinforcements increased. It was found that the density of HRMMC was less than the SRMMC and it decreased with increasing wt% of reinforcements however, the composite contained some porosity percentage (max. value 2.26%), which increased as the wt% of reinforcement increased. The microstructure analysis showed fair distribution with good interface bonding up to 6 wt% bagasse ash.

In recent decade, polymer matrix composites were extensively used in various engineering applications owing to their advanced properties over conventional materials and enhanced performance. This motivated the researchers to generate an extensive study and research work on polymer composites. In recent studies, the erosion properties of the polymer composite attract increasing attention among researchers. The potential enhancement in the erosion resistance property of filled composites tempted the researchers to find the feasibility of using various filler materials in polymer matrix for specific erosion resistance applications. However, only limited numbers of literature are available concerning the tribological performance of the filled composite. Hence in this study, an objective was set to review the various literature that explain the erosion characteristics of filled composites.

“…Aluminum matrix composites are preferred for various applications such as in aerospace, marine and automobile industrials due to their remarkable mechanical and thermal properties. 1 In recent years, the addition of various nano-particles such as SiC, 2,3 TiC, 4 SiO 2 , 5,6 graphene oxide, 7,8 Al 2 O 3 , 9,10 ZrO 2 , 11 fly ash, 10,12,13 and WC 14 as reinforcement agents were popular since they could raise superior properties of the matrix; however, the manufacturing complexity of such materials was the challenge of nano-composites production due to the agglomeration effect of nano-particles in the matrix. Besides, in recent years, vehicle manufacturers are trying various methods to enhance the efficiency of different parts.…”

In this paper, comparative evaluations on the mechanical properties of Al-Si-Cu alloy reinforced by nano-clay mineral particles were carried out. Such nano-composites contained 1 wt% nano-clay particles and were manufactured through the stir casting with various stirring temperatures and times. Mechanical behaviors such as the hardness and compressive strengths, the elastic modulus and wear properties were studied. The microstructural observations were conducted by the optical and the scanning electron microscopy. Field emission scanning electron microscopy (FESEM) images showed that nano-clay particles distributed uniformly in the aluminum matrix for the nano-composite fabricated at 800 ℃ and was stirred for 2 min. Besides, the lower stirring temperature of 750 ℃ caused a degree of clustering with a size of lower than 200 nm in some places. In comparison with the base alloy, an improvement of 5% to 33% in Brinell hardness value observed for various nano-composites. The wear resistance of various nano-composites also increased two to five times regarding the base alloy. The parameter of µ/E. H2 would predict the wear rate for all specimens. It was found that nano-composites fabricated at the temperature of 750 ℃ exhibited the lower porosity content and the higher ultimate compressive strength, and the elastic modulus.
