“…The good bonding between matrix and reinforcement is also important for the mechanical properties of composites Ajay Kumar et al, 2020). The improvement of the mechanical properties of Mg alloy composite reinforced by ZrO 2 particles is mainly determined by the interfacial bonding between the Mg matrix and ZrO 2 particles.…”

“…In the case of FSPed Mg-based composites, the tool geometry and the process parameter optimization (like capping pass, multiple passes) were extensively investigated to improve the mechanical properties (Hashemi and Hussain, 2015;Khodabakhshi et al, 2017;Barati et al, 2019). The distribution of reinforcement and the interfacial bonding between matrix and reinforcement largely determines its mechanical properties Ajay Kumar et al, 2020). The previous researches have focused on FSPed Mg-based composites with the conventional rotation speeds (less than 2,000 rpm) (Hanas et al, 2018;Shang et al, 2019).…”

The nano-ZrO 2-reinforced AZ31 alloy composites were fabricated by friction stir processing with three multi-passes and high rotation speeds. The AZ31/2.14 vol% ZrO 2 , AZ31/4.29 vol% ZrO 2, and AZ31/6.43 vol% ZrO 2 composites were designed. The fine microstructure and uniform dispersion of ZrO 2 particles were observed in the AZ31/ZrO 2 composites. The excellent interfacial bonding was observed between the Mg matrix and ZrO 2. The hardness and tensile properties were enhanced after three cumulative friction stir processing passes. This was attributed to grain refinement and strengthening effects of ZrO 2. The tensile properties and hardness of the AZ31/ZrO 2 composite increased with the increase of volume fraction of the ZrO 2 particles from 2.14 to 6.43 vol%.

“…The growing demands for reducing energy consumption and producing more fuel-efficient vehicles are a big challenge. Cast A356 (hypoeutectic Al alloy containing 6.5-7.5% Si) is widely used for manufacturing aerospace and automotive components due to its high strength-to-weight ratio, good castability, good mechanical properties, and good corrosion resistance [26,27]. Despite several researchers [28][29][30][31] studing the properties and processing parameters to deposit different Al alloys using solid-state techniques, there is no publication discussing the AFSD of cast A356 alloy.…”

In the current investigation, additive friction stir-deposition (AFS-D) of as-cast hypoeutectic A356 Al alloy was conducted. The effect of feeding speeds of 3, 4, and 5 mm/min at a constant rotational speed of 1200 rpm on the macrostructure, microstructure, and hardness of the additive manufacturing parts (AMPs) was investigated. Various techniques (OM, SEM, and XRD) were used to evaluate grain microstructure, presence phases, and intermetallics for the as-cast material and the AMPs. The results showed that the friction stir deposition technique successfully produced sound additive manufactured parts at all the applied feeding speeds. The friction stir deposition process significantly improved the microstructure of the as-cast alloy by eliminating porosity and refining the dendritic α-Al grains, eutectic Si phase, and the primary Si plates in addition to intermetallic fragmentation. The mean values of the grain size of the produced AMPs at the feeding speeds of 3, 4, and 5 mm/min were 0.62 ± 0.1, 1.54 ± 0.2, and 2.40 ± 0.15 µm, respectively, compared to the grain size value of 30.85 ± 2 for the as-cast alloy. The AMPs exhibited higher hardness values than the as-cast A356 alloy. The as-cast A356 alloy showed highly scattered hardness values between 55 and 75.8 VHN. The AMP fabricated at a 3 mm/min feeding speed exhibited the maximum hardness values between 88 and 98.1 VHN.

Mechanical and physical properties of aluminum alloys make them suitable for automotive and other structural applications. The high silicon content in aluminum improves the hardness to a great extent but at the cost of ductility. Herein, the reinforcement of near eutectic Al–Si (ADC12) alloy with the reduced graphene oxide (rGO) is demonstrated. The ADC12 alloy and its composite with rGO are cast using the gravity stir die‐casting process. The structural, mechanical, metallurgical, and tribological characteristics are conducted to understand the role of rGO as a reinforcement phase. The 0.7 wt% rGO as a reinforcement phase to ADC12 alloy reduces the friction and wear volume by 50% and ≈90%, respectively, whereas it improves the hardness by 27%. The high‐resolution transmission electron microscopy (TEM) image reveals the wrapping of microstructural silicon by rGO, which inhibits the growth of primary silicon and improves the interfacial strengthening. The high mechanical strength and low shearing properties of rGO, uniform dispersion in the ADC12 alloy, and restrained growth of primary silicon make the ADC12 alloy‐based composites potential materials for structural and low‐frictional building blocks in a diversified range of applications.
