“…The feed rate mostly in the range of 30-80 mm/min was preferred for the fabrication of various surface composites. In carbon nanotubes/Mg alloy surface composite fabricated through FSP at constant tool rpm and varying feed rates, It was found that composite processed at 25 mm/ min showed the improved distribution of the Multiwall carbon nanotubes reinforcement in the matrix material [18]. In SiC reinforced aluminum surface composite, it [92] was reported that uniform distribution of SiC particles was directly proportional to rotational and traverse speed.…”

“…The mechanical property of Mg-CNT composites has outstanding whereas Mg-Al 2 O 3 composite possesses greater wear resistance [73]. In carbon nanotubes/Mg alloy surface composite fabricated through FSP, the hardness of the fabricated composite was increased up to 92% of the base metal [18]. The surface composite fabricated by reinforcing Al 2 O 3 particle aluminum substrate exhibited enhanced hardness as compared to substrate material [16].…”

“…The use of these alternative reinforcements showed noteworthy enhancement in the properties of the composites as compared to the matrix material. The second strategy is to optimize the properties of composites by using nanoscale particle size of reinforcement materials instead of micron-scale particles [11][12][13][14][15][16][17][18]. The third strategy involves using two or more reinforcing materials to developed hybrid composites.…”

In many applications, surface properties of materials or components are more important than the entire volume material properties. The hardness, wear and corrosion resistance of material mainly depends on the surface properties. Improved surface properties also increased the life span of components. The friction stir process is a novel solid-state processing technique that is widely used for welding difficult-to-weld materials. In this paper, the applications of the friction stir process in surface modifications and fabrication of aluminum matrix surface composites were discussed. The effects of friction stir process parameters, tool design, reinforcement and reinforcement techniques on the surface properties were also reported.

“…Mg-CNT composites have exceptional mechanical properties, but Mg-Al2O3 composites have better wear resistance [53]. The hardness of the created composite was enhanced to 92% of the base metal in the carbon nanotubes/Mg alloy surface composite created using FSP [54]. In comparison to the substrate material, the surface composite created by reinforcing an aluminium substrate with Al2O3 particles showed improved hardness [55].…”

This work is an attempt to fabricate aluminum (AA 5049) matrix composites (AMCs) reinforced with electrospun polyacrylonitrile (PAN) nanofibers and consisting of exfoliated graphite nanosheets (EGNS/PAN) by utilizing friction stir processing (FSP) to improve the mechanical characteristics of AA 5049. PAN and EGNS/PAN nanofibers were fabricated using the electrospinning technique. The average diameter of the electrospun PAN nanofibers is 195 ± 57 nm, and after EGNS incorporation is 180 ± 68nm. The incorporation of nanofiber reinforcement can enhance the mechanical characteristics of AA5049. The mechanical characteristics of AA5049 can be enhanced by the procedure of incorporating nanofibers, making them an ideal choice for applications in the automotive and aerospace industries. PAN and EGNS/PAN nanofiber reinforcement enhanced the hardness to 89 and 98 Hv, respectively. Also, the ultimate tensile strength was raised to 291 MPa and 344 MPa, respectively.

“…So far, a lot of reinforced particles, such as TiC ( Balakrishnan et al, 2015 ; Navazani and Dehghani, 2015 ), TiAlC ( Gobara et al, 2015 ), Al 2 O 3 ( Azizieh et al, 2018 ), B 4 C ( Vedabouriswaran and Aravindan, 2018 ), MWCNT ( Morisada et al, 2006b ; Arab et al, 2017 ), and SiC ( Morisada et al, 2006a ) have been added in Mg matrix by FSP, improving the mechanical properties of the alloys. For example, Navazani and Dehghani (2015) and Balakrishnan et al (2015) studied the microstructure and mechanical properties of AZ31/TiC composites fabricated by FSP.…”

Magnesium (Mg) and its alloys have attached more and more attention because of their potential as a new type of biodegradable metal materials. In this work, AZ31/ZrO2 nanocomposites with good uniformity were prepared successfully by friction stir processing (FSP). The scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to characterize the microstructure of the composites. The mechanical properties, electrochemical corrosion properties and biological properties were evaluated. In addition, the effect of reinforced particles (ZrO2) on the microstructure and properties of the composite was studied comparing with FSP AZ31 Mg alloy. The results show that compared with the base metal (BM), the AZ31/ZrO2 composite material achieves homogenization, densification, and grain refinement after FSP. The combination of dynamic recrystallization and ZrO2 particles leads to grain refinement of Mg alloy, and the average grain size of AZ31/ZrO2 composites is 3.2 μm. After FSP, the c-axis of grain is deflected under the compression stress of shoulder and the shear stress of pin. The ultimate tensile strength (UTS) and yield strength (YS) of BM were 283 and 137 MPa, respectively, the UTS and YS of AZ31/ZrO2 composites were 427 and 217 MPa, respectively. The grain refinement and Orowan strengthening are the major strengthening mechanisms. Moreover, the corrosion resistance in simulated body fluid of Mg alloy is improved by grain refinement and the barrier effect of ZrO2.
