“…Due to non-wetting conditions between monolithic phases, it is difficult to fabricate carbon materials reinforced AMCs with high mechanical properties using traditional casting technologies [12]. To overcome this issue, researchers have proposed various modified processing methods, such as squeeze casting [13,14], liquid infiltration [15][16][17] and powder metallurgy [18][19][20][21]. On the other hand, the interfacial reaction plays a critical role in the mechanical properties of composites.…”

The short carbon fiber reinforced 2024 Al composites were fabricated through powder metallurgy. The effect of short carbon fiber content on the interfacial microstructure and fracture behavior of the composites at different temperatures were investigated. The results showed that the dislocation accumulation was formed in the aluminum matrix due to the thermal expansion mismatch between carbon fiber and aluminum matrix. With the testing temperature increasing, the size of interfacial product Al4C3 and precipitates Al2Cu became larger, and the segregation of Al2Cu was found coarsening around Al4C3. The addition of short carbon fiber improved the hardness and modulus of the aluminum matrix in the vicinity of the interface between carbon fiber and aluminum matrix. Compared to the matrix 2024 Al, the yield strength and ultimate tensile strength of the composites first increased and then decreased with increasing short carbon fiber content at room temperature 423 Kand 523 K. The fracture surface of the composites at room temperature was characterized by shear failure of fiber, while the interface debonding and fiber pulled-out became predominant fracture morphologies for the fracture surface at increased temperatures.

“…A number of techniques have been developed to manufacture metal matrix composites (MMCs), including powder metallurgy process, 14,15) hot extrusion, 16) hot rolling 17) and casting method, 18) however, powder metallurgy process costs high energy, hot extrusion and rolling methods are difficult to fabricate complicated shaped composites. Though casting method possesses many merits and it is an easy way to fabricate composites, the not well wettability between fibers and aluminum makes fiber hard to uniformly disperse in the matrix.…”

Carbon fiber reinforced pure Al, A336 alloy and carbon fiber-carbon nanofiber reinforced A336 alloy composites were successfully fabricated by low-pressure infiltration process, aiming for development the carbon fiber reinforced aluminum matrix composites with high thermal conductivity and mechanical property used as functional materials and structural materials, respectively. Carbon fiber of 10 vol% and hybrid carbon fiber-carbon nanofiber of 10 vol% were used to fabricated preforms for the low-pressure infiltration process. Afterwards, pure Al and Aluminum alloy under a temperature of 1073 K were infiltrated into the preforms under an applied pressure of 0.4 MPa in Ar environment. Microstructural and mechanical performances of the composites were investigated. Microstructure observations indicated that SiO 2 binder was coated on the surface of carbon fiber and distributed at the corner of carbon fibers in carbon fiber preform. Carbon nanofibers were agglomerated at the corner of carbon fibers, and some were dispersed on the surface of carbon fiber in the hybrid preform. In composites, carbon fibers were homogeneously distributed in the matrix. Further Vickers hardness test results showed that the hardness of carbon fiber reinforced pure Al composite increased by 76% compared to pure Al, and carbon fiber reinforced A336 alloy composite increased by 11.1% compared to A336 alloy. The thermal conductivity (TC) test result illustrated that the thermal conductivity of carbon fiber reinforced pure Al and A336 alloy composite was 245.8 W/(m·K) and 113.5 W/(m·K), respectively, and the thermal conductivity of carbon fiber-carbon nanofiber reinforced A336 alloy composite was 98.4 W/(m·K).

“…Due to the high aspect ratio of CNTs, attaining a homogenous dispersion from these reinforcing materials is rather challenging (Carvalho et al, 2013;Khodabakhshi et al, 2017). Therefore, several methods have been introduced and implemented such as mechanical alloying (MA) (Wang et al, 2009), squeeze casting (SC) (Alhashmy et al, 2015), spread dispersion (SD) (Liao & Tan, 2011), accumulative roll bonding (ARB) (Yoo et al, 2012), equal channel angular pressing (ECAP) (Zare et al, 2016), spark plasma sintering (SPS) (Najimi & Shahverdi), high-pressure torsion (HPT) (Phuong et al, 2014) and friction-stir processing (FSP) (Lim et al, 2009). Among these, FSP as developed by Mishra et al (2003) based on the friction-stir welding (FSW) technology is a promising route for the purpose of surface modifications.…”

Multipass friction-stir processing was employed to uniformly disperse multiwalled carbon nanotubes (MW-CNTs) within an Al-Mg alloy metal matrix. Decomposition of MW-CNTs occurs in situ as a result of solid-state chemical reactions, forming fullerene (C60) and aluminium carbide (Al C ) phases during reactive high temperature severe plastic processing. The effects of this decomposition on the microstructural features, dynamic restoration mechanisms and crystallographic microtextural developments are studied for the first time by using electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM) analysis. The formation of an equiaxed grain structure with an average size of ∼1.5 μm occurs within the stirred zone (SZ) under the influence of inclusions which hinder grain boundary migration via Zener-Smith pinning mechanisms during the discontinuous dynamic recrystallisation (DDRX). Formation of two strong Cubic and Brass microtextural components in the heat affected zone (HAZ) and thermomechanical affected zone (TMAZ) was noted as compared to the completely random and Cube components found in the base and SZ regions, respectively. The microstructural modification led to hardening and tensile strength improvement for the processed nanocomposite by ∼55% and 110%, respectively with respect to the annealed Al-Mg base alloy.
