“…It is noticeable that this linear plot does not cross zero point. The deviation is possibly attributed to the measurement error of wear scar, which were also presented in other reports [11,29]. Furthermore, the tribological behaviors of the bulk amorphous steel were also examined at high temperatures of 373 K, 473 K, and 573 K, respectively, considering their possible high temperature applications due to the relatively high thermal stability among various BMG systems.…”

“…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.

“…The improvements in properties are due to the presence of Al 2 Cu phases, partial refinement of D-Al dendrites and also the microstructure becomes fine with decreasing DAS [2]. This may also be due to solid solution strengthening and precipitation hardening [3,11]. Similiarly, the effect of Mg addition on the mechanical properties of A356 alloy is shown in Fig.…”

In the present study, the effect of copper (Cu) and magnesium (Mg) addition on the microstructure and mechanical behavior of A356 alloy were investigated. Results indicate that, the minor additions of Cu in the range of 0.1-0.5% improves the mechanical properties. This is due to the partial refinement of D-Al dendrites and solid solution strengthening and precipitation hardening. Also, addition of Mg (0.3-0.7%) results in improvements in strength and hardness at the expense of ductility. This improvement is probably due to the conversion of unmodified acicular silicon (Si) to lamellar, partially rounded and even a fibrous structure.
