Summary: Researchers created composites as alternatives to existing engineering materials driven by the need for fresh, promising materials with superior mechanical and tribological properties. In this review study, a comprehensive evaluation of the sliding wear response of aluminium matrix composites (AMCs) in a dry environment was attempted using a pin-on-disc wear tester. The wear performance of Al monolithic alloy and its composites was discussed in relation to varying process parameters and the concentration of different particle reinforcements, presenting the effects of various intrinsic and extrinsic variables on wear characteristics.

Summary: Heat sinks are commonly used for cooling electronics and high-power electrical systems, requiring materials with high thermal conductivity and coefficients of thermal expansion matching to semiconductor chips and ceramic substrates. Traditional materials are inadequate, leading to the development of new composite materials like metal matrix composites (MMCs). By selecting proper metallic matrix and optimizing the reinforcements, desired properties can be obtained.

Summary: Novel aluminium matrix composites with high entropy alloy reinforcement phase particles were fabricated and studied for their microstructure, mechanical properties, and response to wear and corrosion. It was found that no secondary intermetallic phases were formed in the microstructure. The hardness and wear resistance of the composites increased with the increase in high entropy alloy particles, while the composites exhibited susceptibility to localized corrosion. Nanoindentation techniques and creep response provided insights into the deformation nature of the materials.

Summary: The study investigated the effect of heat treatment on wear and friction behavior of sillimanite/LM30 aluminium matrix composites at elevated temperatures. The addition of sillimanite particles improved wear resistance and coefficient of friction of the composites, and the heat treatment further enhanced wear resistance and coefficient of friction. Wear analysis showed a transition from mild to severe wear behavior beyond 200 degrees C.

Summary: In this study, commercial 6061 Al alloy and SiCp reinforced 6092 Al matrix composite were joined by friction-stir welding with different tool offsets. The results showed that offsetting the pin to the Al alloy side significantly reduced tool wear, while maintaining the joint's ultimate tensile strength. The study also found that as the tool offset increased, the wear length of the pin and shoulder decreased, thereby increasing the safety of the welding.

Summary: Researchers have fabricated lightweight hybrid composite brake discs using a A357/SiC aluminium matrix composite (AMMC) top layer and an AA6082 Al alloy bottom base by friction-stir processing. These brake discs demonstrate excellent wear and friction performance in full-scale dynamometer braking tests for city rail vehicles. The improved microstructures and properties, such as the presence of thermally stable and hard SiC particles enhancing wear resistance, have been identified as the main factors contributing to their outstanding performance.

Summary: This paper provides an overview of the surface properties and wear behavior of metal matrix nanocomposites (MMNCs), focusing on manufacturing routes, nanoparticles, and dominant wear mechanisms. It is found that ceramic-reinforced composites generally show better wear resistance compared to carbon-based nanomaterials. Hybrid MMNCs, especially those combining ceramic and carbon-based particles, are promising materials for improving surface resistance.

Summary: The study demonstrates the positive impact of corundum reinforcement on dry sliding wear behavior of LM30 aluminum alloy composites. The composites prepared by stir casting process exhibit uniform distribution of particles and refined microstructure, leading to improved hardness. The addition of corundum results in lower wear rate and coefficient of friction in the composites, and wear mechanism is pressure-dependent.

Summary: The effect of artificial aging heat treatment on the microstructure and corrosion behavior of a Al-Zn-Mg-Cu matrix composite was investigated. It was found that the presence of nickel-aluminide reinforcement resulted in the formation of a bimodal microstructure and increased the hardness and strength of the composite. However, aging heat treatment had a negative impact on the corrosion resistance of the composite.

Summary: An Mg-Si-based 6082 aluminium metal matrix composite reinforced with varying concentrations of CoCrFeMnNi high-entropy alloy particles (HEAp) was processed through stir-squeeze casting. The composites were heat treated to examine the age-hardening effect on microstructural changes, fracture mechanism, and the interface between HEAp and aluminium matrix. The evolution of microstructure and topography of the fractured surface was investigated to characterize the precipitate and intermetallic compound formed at the Al/HEAp interface. The tensile test was performed to investigate the correlation between tensile strength and artificial ageing. Under the T6 condition, the composites exhibit superior mechanical properties, such as improved hardness, yield strength, and ultimate tensile strength. However, the ductility of the composites is lower compared to the as-cast condition due to the formation of precipitates.
