“…The shape of sand also influences the packing density and sand surface area and the consumption of binder is proportionate to the sand surface area. The best foundry sand is generally rounded with medium to high sphericity grains [7,16,17,18]. The river sand has angular grains, low sphericity mixed with angular grains, medium sphericity as shown in Fig.…”

Sand casting is a metal casting process to make a component by pouring molten metal into the sand mold. The casting process, the sand is the fundamental material used for mold making. The sand used is generally silica sand, river sand, mountain sand, and beach sand. The sand for molding must have requirements such as having formability, suitable permeability, good distribution of sand grain size, resistance to high temperatures, suitable binder composition, and sand must be cheap. This study investigated to determine the potential of Krueng Mane river sand in Aceh Indonesia for its possible use for metal casting. The important properties studied are moisture content, total clay content, grain fineness number, and grain shape. Tests are carried out following the standards and procedures defined by the American Foundrymen’s Society (AFS). Results obtained revealed that the river sand has average moisture content of 7.78 %, clay content of 3.20%, and grain fineness number (GFN) of 46. Krueng Mane river sand will be suitable for casting of casting of light steel, heavy grey steel, medium grey iron, and non-ferrous metals, with the addition of binding agent in suitable proportion.

“…Conversely, the responses of apparent porosity was set to minimum, while that of % elongation (%), energy at maximum tensile stress (J), fracture toughness (KiC MPam 1/2 ), young modulus (MPa) and tensile strength (MPa) were set to maximum. The goal of numerical optimization is not to maximize the level of desirability, generally the factor settings that result in the highest desirability is acceptable for numerical optimization [30,31]. From the numerical optimization report, one solution that best meet the target criteria is chosen as the optimal solution.…”

“…From the numerical optimization report, one solution that best meet the target criteria is chosen as the optimal solution. This is most times the solution that have the highest level of desirability, indicating there is an island of acceptable performances [31,32]. The optimal solution could be presented graphically using contour and overlay plots.…”

Hybridization of aluminium matrix composite is with a view to offset the properties deficient in one composite reinforcement. The present investigation involves a comparative study of AA6063 matrix composites with single reinforcement of Al2O3, SiC, graphene respectively and various hybridized proportions of the same reinforcements. Physical (density and %porosity) and mechanical (tensile strength, fracture toughness, %elongation, elastic modulus, etc.) properties of composites developed via solidification processing technique were evaluated. The porosity of all the composites falls below the maximum acceptable limit for cast metal matrix composite. Maximum values for UTS, %elongation and absorbed energy at maximum stress was obtained by hybrid composite with 4wt% Al2O3, SiC and 2wt% graphene, while the composite with the highest single reinforcement of graphene have the highest value for elastic modulus and fracture toughness. Numerical optimization results show that a matrix and hybrid reinforcements contents of AA6063 (91.413wt.%), SiC (3.679wt.%), Al2O3 (0.277wt.%), and graphene (4.632wt.%) respectively, will result in optimal values for the evaluated properties.
