“…Because of its exceptional qualities, such as low density, high specific strength, corrosion resistance, high stiffness, good stability at high temperatures, reduced part weight, low thermal shock, and the capacity to improve mechanical properties, AMC is widely used in a variety of applications [1][2][3]. MMC is a wide-reaching material for various applications, such as defense, transport, maritime, aerospace, medical, and other industry [4,5]. Aluminum alloys have shown to be particularly promising for reducing automotive weight in recent years.…”

Due to their excellent properties, the requirement for materials with higher characteristics has transformed primary alloy into composite materials. Composites are particularly essential for various applications in numerous engineering purposes because of their superior mechanical, physical, and machining qualities. Compared to traditional materials, aluminum composite has various advantages and superior characteristics. To reduce production costs and obtain the desired properties, the researchers developed a hybrid aluminum matrix composite (HAMC), an AMC with two or more types of reinforcement. Further studies were conducted to improve the qualities and manufacturing processes of composites to improve their properties. Various methods are available to HAMC manufacturing, and different manufacturing methods result in different characteristics of HAMC composites, viewed from physical properties, mechanical properties, and production cost. In addition, differences in the type, size, and amount of reinforcement produce various hybrid composite properties, especially in the physical properties, mechanical properties, and tribological behavior of HAMC. This work presents a comprehensive review of recent progress in HAMC study with various reinforcement particles, manufacturing techniques, physical, mechanical, and tribological properties of HAMC. On the other side, this work provides discussion for application, challenges, and future work conducted for HAMC development.

“…Therefore, researchers are looking for other alternatives to reduce production costs while still maintaining their mechanical properties. One such alternative is to use natural materials that are readily available in nature, such as fly ash [9], natural rubber [10], natural fibres [11], and sea sand [12]. Using sea sand reduces the cost of aluminium goods and produces low-cost by products.…”

“…As a result sea sand has the potential to be employed as reinforcement in aluminium matrix composites because it is a natural material that contains ceramic [14,15]. Previous research shows that concrete with sea sand has been studied by Akbar et al [12]. The results state that the presence of sea sand as an aggregate in concrete results the concrete is improving hardness.…”

The goal of this research was to determine the impact of cold forging on the mechanical characteristics and microstructure of Al MMCs at various sea sand percentages and forging deformations. The wettability of sea sand was improved by applying an electroless coating just before the stir-casting procedure. Using the stir casting technique, a composite material of Al6061 and sea sand was fabricated at several percentages of sea sand in weight, such as 2, 4, and 6%. In addition, open-die forging in cold settings was studied to learn more about the deformation characteristics of Al6061-sea sand composite. Composites were tested for density, porosity, microstructure, macrostructure, and hardness. The behaviour of microstructures was studied with an optical microscope. Brinell hardness readings taken according to ASTM E-10 were used to characterize the composite. The stir casting method was used to investigate and analyse the samples characteristics. More sea sand particles are distributed throughout the matrix as the composite’s density decreases. Increases in porosity are associated with an increase in reinforcement percentage, as this leads to more matrix-reinforcement surface contact and hence more porosity. The hardness diminishes with an increase in the proportion of sea sand particles. The mechanical qualities of the composite were enhanced by an oxide compound found on the sea sand. Evidence suggests that forging enhances mechanical and microstructure qualities.

“…However, the liquid state processing method, especially stir casting, is preferred due to its ease of operation and ability to produce large quantities of aluminum [11]. Despite its convenience, stir casting has a weakness, namely the distribution of particles that are not homogeneous in the material [1,12]. The non-uniform distribution of particles results in a decrease in the strength of composites that prevents the desired properties from being achieved.…”

The increasing demand for lightweight material specifications has forced researchers to develop lightweight materials that are inexpensive, can be produced on a large scale, and are environmentally friendly. One solution that has been developed is an aluminum composite reinforced with sea sand. Indonesia has the second longest coastline in the world, which means that the country is rich in maritime resources, one of which is sea sand. The ceramic contents of SiO2, SiC, and Al2O3allow sea sand to be used as a reinforcement in aluminum composites for engineering purposes. The most effective manufacturing method of AA6061–sea sand composites is stir casting, but the homogeneity and distribution of particles are the main disadvantages of the stir casting method. Various factors affect particle distribution and homogeneity, one of which is the flow during the stirring process. The increase in turbulent flow in the stirring process affects the homogeneity and distribution of the particles. One way to create a turbulent flow when stirring is to add baffles. This paper examines the effect of adding baffles during the stir casting process on the mechanical properties of AA6061–sea sand composites. The mechanical properties of AA6061–sea sand composites were characterized using the Brinell hardness test according to ASTM E-10. The test results show that the addition of baffles during the stir casting process decreases the hardness of the AA6061–sea sand composites due to the turbulent flow that occurs. This makes the material more porous, which makes the AA6061–sea sand composites less hard. Doi: 10.28991/CEJ-2022-08-08-04 Full Text: PDF
