This study focused on improving the mechanical strength and wear resistance of aluminum matrix composites (AMCs) produced by powder metallurgy, which are critical in industrial applications. In this review study, studies involving the preparation and characterization of aluminum based composite materials reinforced with Al2O3, SiC, B4C and MgO powders using the powder metallurgy method have been comprehensively evaluated. Literature shows that changes in sintering time, temperature, and composition of powders can affect critical properties such as material density, hardness, and wear resistance. In general, the increase in sintering time and sintering temperature generally increased the density and reduced the amount of porosity of composite materials consisting of aluminum-based Al2O3, SiC, B4C and MgO powders. Increasing the compaction pressure generally increased the material density and created a more homogeneous structure. When the properties of each material were examined, it was determined that SiC and B4C provide higher strength, hardness and wear resistance, and therefore can be preferred especially in high-performance applications such as automotive, aerospace, defense industry and cutting tools.
