ABSTRACTThe aim of this research is to study the mechanical properties and wear behavior of aluminum composite material (AMCs) reinforced with silicon carbide particles with varying percentages (0, 3, 6 and 9) wt. %. These composites samples were prepared by stir casting process. Tensile strength, compression strength, hardness and wear resistance of the prepared composites were analyzed. The result showed that adding SiC reinforced in Al matrix increased tensile strength, compression strength, wear resistance and hardness with increased wt. percentage of silicon carbide reinforced AMCs. Maximum tensile and compression strength and hardness showed at 9 wt. percentage SiC reinforced AMCs.

Properties Of Composites

In this research aluminum matrix composites (AMCs) was reinforced by titanium carbide (TiC) particles and was produced. Powder metallurgy technique (PM) has been used to fabricate AMCs reinforced with various amounts (0%, 4%, 8%, 12%, 16% and 20% volume fraction) of TiC particles to study the effect of different volume fractions on mechanical properties of the Al-TiC composites. Measurements of compression strength and hardness showed that mechanical properties of composites increased with an increase in volume fraction of TiC Particles. Al-20 % vol. TiC composites exhibited the best properties with hardness value (97HRB) and compression strength value (275Mpa).

Aluminum is a material with advantageous properties such as lightness, good conductivity, high plastic deformation ability, and superior corrosion resistance. However, aluminum and many aluminum alloys have disadvantages in terms of mechanical properties such as hardness, tensile strength, and wear resistance. To overcome this disadvantage of aluminum, it is a good method to add ceramic particles to the matrix. For this purpose, in this study, B4C (boron carbide)-reinforced AA2014 aluminum matrix composites were fabricated at 3%, 5%, and 7% reinforcement ratios using the stir casting method. Tensile tests, wear tests, cutting force measurements, and microhardness measurements were performed to determine the fabricated composite materials’ mechanical properties. Scanning electron microscopy and optical microscopy were used to analyze the microstructure of composite. X-ray diffraction analysis was utilized to study the phase identification. As a result of the study, it was observed that with the increase in the B4C reinforcement ratio, the mechanical properties of the aluminum matrix composite material, such as wear resistance, cutting strength, and hardness, increased. On the other hand, the change in tensile strength did not occur in this way. Tensile strength first increased and then decreased. The highest value of tensile strength was achieved at 5% B4C reinforcement. X-ray diffraction results showed that AA2014 and B4C were the fundamental elements in composites and are free from intermetallics.

Aluminum matrix composites reinforced by silicon carbide particles (SiCp/Al) were prepared using microwave sintering. The hardness, bending strength and compression strength of sintered composites had been measured. The results showed that SiCp/Al composite can be sintered by microwave in very short time. The oxidation or plating copper in silicon carbide surface can improve the mechanical properties of composites.

<p class="AMSmaintext">Aluminium6061 alloy composites containing various volume fractions of Silicon Carbide (SiC) particles (0, 5%, 10%, 15%, 20% and 25%) were prepared by stir casting method. In the current study,<strong> </strong>microstructures and mechanical properties of cast silicon carbide (SiC) reinforced aluminum matrix composites (AMCs) were investigated. Optical microscopic examination, SEM, tensile strength test, hardness test and elongation test were carried out. The results showed that with the addition of SiC reinforcements in Aluminum6061 matrix increased hardness and tensile strength however, decreased elongation at 25% SiC reinforced AMC. Hardness and tensile strength were observed to be are maximum at 25% SiC and elongation is minimum at 25% SiC. Microstructural observation confirmed clustering and homogeneous distribution of SiC particles in the Al6061 matrix.</p>

In this study, functionally gradient aluminum reinforced by Silicon carbide particles (FGMSiCp/Al) composites are prepared by microwave sintering and pressureless sintering processing. The sintering behaviors, mechanical properties of composites were measured, and microstructure was observed by optical microscope and SEM. The results showed that the density of sintered samples which prepared by microwave sintering were better than that presureless sintering one. The highest density of sintered sample by microwave sintering reached 2.64 g/cm3, the relative density was 95.65%. Whatever preparing process, the mechanical properties of sintered samples were related to the temperature. The distribution of silicon carbide particles is uniform in the aluminum matrix, however, slight agglomeration can be observed. The interface between other layers is not obvious except interface between Al and 5% SiC/Al layer.

Aluminium/graphite composites are the need of modern times for addressing the fuel saving issues. The graphite in such composites act as solid lubricant and it reduce external fuel requirements. But such composites are having degraded mechanical properties due to the graphite content in composite. In order to solve the negative effect of graphite on mechanical properties of LM13/Gr self-lubricating composite this study was conducted to find out the mechanical properties of LM13/B4C/Gr Metal Matrix Composites. Boron carbide was selected as reinforcement because of its better reinforcement properties compared to alumina and silicon carbide. The properties of the hybrid composites were compared with the LM13/Gr self-lubricating composite to study the enhancement in mechanical properties that has been caused by the boron carbide particles. Using computerized universal testing machine and rock-well hardness tester mechanical properties such as hardness and tensile strength were tested. Pin on disk testing machine was used to analyse the wear behavior. The test results indicates that by raising weight % of boron carbide particles in the LM13, tensile strength and hardness of the hybrid composites was increased compared to self-lubricating composite accompanied by better tribological properties.
