“…However, there was no considerable advantage in adding nano SiC particles to the aluminium matrix at high creep rates. Similar studies have been performed on the creep properties of aluminium composites reinforced with SiC nanoparticles [2-4], Al 2 O 3 nanoparticles [5], boron carbide nanoparticles [6,7], and carbon nanotubes [8-11].…”

“…In addition to the reinforcing material, the fabrication technique is of critical importance. Metal-matrix composites are fabricated using solid, semi-solid, and liquid base techniques, with each having some advantages and disadvantages [11]. Metal Matrix Composites (MMCs) fabricated by the liquid and semi-solid methods have usually higher mechanical strength due to the formation of strong bonds between the constituting materials.…”

“…Salarieh et al [17] produced Al-Ti composites using the composting method and observed some intermetallic compounds in the final microstructures, despite reaching higher hardness, tensile strength, and toughness. On contrary, solid-state techniques, such as powder metallurgy, have some limitations in the size, content of the reinforcements, and mechanical strength of the produced composites [11]. Rahmani et al [18] investigated the effect of compaction speed, size, and content of reinforcing particles on the corrosion resistance of Mg-B4C composites.…”

Multi-walled carbon nanotubes (MWCNTs) possess outstanding physical and mechanical properties, making them suitable as reinforcing materials for metal-matrix composites. However, their creep resistance has not been studied well. In the present study, aluminium A356 composites reinforced with various weight percentages of MWCNTs were fabricated using the stir casting technique. The surface coating was applied to enhance the wettability of carbon nanotubes. Tensile experiments, fracture analysis, creep tests, and microstructural analyses were performed on the produced composites. Aluminium samples reinforced with 0.2 weight percentage of coated MWCNTs showed to have higher hardness (14%), yield strength (36%), ultimate tensile strength (20%), elongation at break (16%), and creep resistance (30%) compared to that of composites reinforced with uncoated MWCNTs.

“…Metal Matrix Composites (MMCs) have excellent impact resistance, tensile strength, and wear resistance. Composites are more extensively used than traditional materials because of their adaptability in extending mechanical properties [1]. Aluminum matrix composites have developed a rm place in the lightweight materials category due to a wide range of desirable properties, including low density, good wear resistance, and corrosion resistance [2,3].…”

Due to their lightweight, new classes of materials, including aluminumbased Metal Matrix Composites (MMCs), have been popular in recent years in various industries, including aircraft and automobiles. Because of its low cost and ease of availability, aluminum alloy (LM13) MMCs were developed using Rice Husk Ash (RHA) as reinforcement in this study rather than traditional reinforcement, and composites were prepared using the stir casting technique. LM13-15wt.%RHA composite was chosen for the present machining study. The Central Composite Design (CCD) with three input parameters at three levels based on the best outcomes was adopted for this experimental study. A mathematical model was developed to predict the machining responses of Material Removal Rate (MRR) and surface roughness. The most signi cant variables were evaluated using ANOVA. The main and interactive e ects of the input variables on the predicted responses are determined. The experimental and predicted values are nearly identical, indicating that the developed models can accurately predict responses. The optimal value of the turning parameters was obtained from desirability analysis. The obtained desirability value for turning parameters is 0.863, and for output response, the desirability value for surface roughness and MRR is 0.71663 and 0.747491, respectively, and the combined desirability is 0.731898.

Aluminum and its alloys have become the most popular materials in applications aiming to provide lightness due to their low density. However, the low mechanical properties compared to other competitors are among the disadvantages of aluminum and its alloys. This is an important motivation factor in researching strength increasing mechanisms in aluminum and its alloys. In this study, the effects of reinforcement ratio and type on the microstructure, mechanical properties, and wear behavior of the AA7075/B4C composite produced by squeeze casting method were investigated. Two types of materials were produced and compared—non-reinforced AA7075 alloy and AA7075 allo matrix composite reinforced by 4, 8, 10, and 12 wt% B4C. Microstructures of two materials were analyzed by optical microscope, scanning electron microscope and energy distribution spectrometer. In addition, the mechanical and tribological properties of these materials were investigated. Microstructure and scanning electron microscope analysis reveals that the increasing B4C reinforcement ratio increased the tendency of agglomeration in the matrix. Although B4C reinforcement tends to agglomerate, B4C reinforcement positively affected the AA7075 alloy's hardness, tensile and bending strengths, elasticity modules, and wear resistance.
