“…The low mechanical properties of Al and its alloys can be greatly enhanced by incorporating hard ceramic reinforcing particles. Al matrix composites (AMCs) have been of importance for a long time due to their superior mechanical properties as compared to conventional monolithic Al without sacrificing the corrosion resistance of Al [5,6]. The improved properties of AMCs are strongly related to the characteristics of the matrix and reinforcement as well as the reinforcement/matrix interface.…”

“…Due to the easily oxidized nature of aluminum, frictional heating during sliding under high load that was caused the oxide film on the surface of the pin sample generated. Studies by Lashgari et al [27] and Dwivedi et al [28] showed that the existence of the oxide film improved the wear behavior and reduced the friction coefficient because of the lubrication effect. At the same time, the oxide film prevented metal-to-metal contact, resulting in a low wear volume.…”

This paper investigated the influence of heat treatment (T6) on the dry sliding wear behavior of SiCp/Al-5Si-1Cu-0.5Mg composite that was fabricated by electromagnetic stirring method. The wear rates and friction coefficients were measured using a pin-on-disc tribometer under loads of 15-90 N at dry sliding speeds of 100 r/min, 200 r/min, and 300 r/min, over a sliding time of 15 min. The worn surfaces and debris were examined using a scanning electron microscope and was analyzed with an energy dispersive spectrometer. The experimental results revealed that SiCp/Al-5Si-1Cu-0.5Mg alloy treated with T6 exhibited lower wear rate and friction coefficient than the other investigated alloys. As the applied load increased, the wear rate and friction coefficient increased. While, the wear rate and friction coefficient decreased with the sliding speed increasing. The morphology of the eutectic silicon was spheroidal after the T6 heat treatment. SiCp particles and Al 2 Cu phase can be considered as the main raisons for improving the wear behavior. Abrasion and oxidation were the wear mechanisms at low load levels. However, the wear mechanisms at high load levels were plastic deformation and delamination.

AlMg alloys close to ¢-Al 3 Mg 2 intermetallic phase were processed by neutral gas coverage melting process of pure elemental Al and Mg with the composition of Al40 mass% Mg. Mechanical milling was applied in order to convert the pre-alloyed ingots to nanocrystalline or amorphous alloy. X-ray diffraction and transmission electron microscopy (TEM) tests were carried out to investigate the formation of Al 3 Mg 2 single phase nanoparticle. Having prepared the single phase intermetallic, it was added to the pre-alloyed matrix powder of Al4.5 mass% Cu, in different contents. The effect of the reinforcing agent on the microhardness and wear behavior of the nanocopmosites were studied thoroughly with the aid of press-sinter methodology and quantitative data recorders via pin-on-disk wear test. The results of microhardness tests revealed that the hardness of nanocomposites is significantly improved with increasing reinforcement content with in the matrix. The coexisted wear mechanisms, mainly delamination and abrasive, of the consolidated nanocopmosites were investigated through scanning electron microscopy (SEM) and TEM observations.
