Characterization of Hybrid Silicon Carbide and Boron Carbide Nanoparticles-Reinforced Aluminum Alloy Composites

Creep behavior and wear resistance of Al 5083 based hybrid composites reinforced with carbon nanotubes (CNTs) and boron carbide (B4C)

“…Recently, hybrid aluminum matrix composites, simultaneously reinforced with micro-nano hybrid reinforcements, have been extensively studied due to their superior wear and mechanical properties over single reinforcement reinforced composites [4,5]. Since 1970, the research in hybrid aluminum matrix composites has been in progress [6].…”

Microstructure and mechanical properties of the semisolid slurries and rheoformed component of nano-sized SiC/7075 aluminum matrix composite prepared by ultrasonic-assisted semisolid stirring

“…Conventional stirring could also mix small particle into the melt, but when the stirring was stopped, the small particles returned to the surface or clustered. Ultrasonic treatment can create transient cavitation and acoustic streaming to disperse uniformly the nano-sized ceramic particles [20,23,[31][32][33]. Dispersion effect of ultrasonic wave can be illustrated by the results of the small illustration experiment, as shown in Fig.4.…”

“…Ball milling of the starting nano-sized Al 2 O 3 and Cu powder exhibits an improvement in dispersing nano-sized ceramic particle [21,22]. Ultrasonic treatment was also a promising technology to disperse nano-sized ceramic particles such as nano-sized SiC [21] or hybrid SiC and B 4 C [23]. Some significant results including a good dispersion of nano-sized SiC or hybrid SiC and B 4 C, and enhanced strength have been achieved.…”

Aluminium matrix hybrid composites: a review of reinforcement philosophies; mechanical, corrosion and tribological characteristics

“…A number of review papers on the mechanical behaviour, machining and tribological properties of aluminium hybrid composites reinforced with two different synthetic ceramic materials have been reported by some authors [25,[39][40][41]. The authors concluded that the reinforcing materials have significant effect on the improvement of the tensile strength, hardness machinability and tribological properties of the composites.…”

“…The fracture toughness and ductility of DRAMCs have reportedly been improved without significant drop in strength when nanoparticulates are used as reinforcing materials [1,7,[24][25][26]. This development seem to be an interesting one however, high cost and availability of nano-particulates seem to be a limiting factor especially in developing countries where AMCs are produced.…”
