Fabrication of Al-based hybrid composites reinforced with SiC whiskers and SiC nanoparticles by squeeze casting

Nano and hybrid aluminum based metal matrix composites: an overview

“…Eutectic reaction occurred during milling increases the sintering rate due to increased diffusion rate for the composite powder which in turn gives finer microstructure, high hardness and less pores. Zhang et al [10], Sureshbabu et al [11], Feng et al [12] and Geng et al [34] have used squeeze casting to fabricate Al based hybrid composite which distribute nano particles homogeneously that increased strength and resistance to fracture propagation. Reddy et al [35] produced aluminium matrix hybrid (Al 3 Ni/Al 2 O 3 ) nano composite by mechanically activated solid state combustion in-situ method without affecting nano-structure.…”

“…The investigations on SiC reinforcement have found that particle size less than 10 lm gives better mechanical properties. Hence hybridization of SiC w + SiC nano particulates can further enhance properties of composites [10].…”

“…e.g. Car engine block in which graphite and alumina are used in the form of particulates [8][9][10]. Hybrid metal matrix composites shows improved mechanical properties due to reduction in meniscus penetration defect and reduced formation of inter-metallic component at interfaces because of increased interfacial area [11].…”

Microstructures in centrifugal casting of SiCp/AlSi9Mg composites with different mould rotation speeds

“…Metal matrix composites have been produced via different routes mainly powder metallurgy, spray casting, liquid infiltration with pressure or without pressure and stirring casting techniques [1][2][3][4][5][6] . Stirring casting technique [7] are simple and economical due to the possibility of utilizing the conventional casting equipments without limitation in size and shape of components.…”

Optimization of Squeeze Casting Parameters for 2017 A Wrought Al Alloy Using Taguchi Method

“…Many research works on squeeze casting parameters of aluminium alloys [11][12][13] and magnesium alloys [14,15] as well as their composites [16][17][18] have been reported in the literature. The intensity of applied pressure, the melt temperature and the die temperature have been shown to be among the most important parameters affecting the quality of squeeze cast components [7,19].…”
