“…Several approaches using liquid-based processes have been tested: stir-casting, die-casting, and squeeze casting. Stir-casting A356-based composites with 2 wt% Ni-plated CNTs improved hardness values by 28% [6]. By die-casting A356 composites with 1 wt% SiC-coated CNT reinforcement, yield strength and tensile strength were improved by 25% and 16%, respectively [13].…”

“…Prior studies have focused on one of two Al alloys as matrices: A356 [6,7,13,14] and Al239D [4]. The strengthening mechanisms within these alloys are complex owing to the precipitation of metallic compounds, effects of heat treatments, and complex microstructures.…”

“…Usually, the semisolid material is then injected into hardened steels, dies as final stage process. The advantages of semisolid processing include low shrinkage and porosity, nonturbulent filling and lower processing temperature (Abbasipour et al 2010;Heinrich and Gonasagren 2012 …”

Fundamentals of metal matrix composites are overviewed. The various light metal matrix systems (particularly Al and Mg) and the different types of reinforcements used are mentioned. The various composite production methods are described. Strengthening mechanisms that define the enhancement in properties of composites are discussed. The microstructural and mechanical properties of the composites are summarized. In addition, the several disadvantages encountered in MMCs due to ceramic reinforcement addition are understood from interfacial characteristic/properties. Keywords

“…SiC particles of 2.5 vol. wt% preheated to a temperature of 1100 • C for 2 hours to oxidize their surfaces were added into the vortex with mechanical stirring at 500 rpm according to Abbassipour et al [14] for about 5 minutes. Actual mixing occurs when the slurry is at semisolid form.…”

This paper studies the influence of the grit size of silicon carbide particles on the mechanical and electrical properties of stir cast aluminum matrix composites. A two step-mixing method of stir casting technique at (500 rpm) has been adopted. Type 1170 Al with (99.66 % C.P) and silicon carbide (SiC) particulates of 240 grit size (45 μm), 320 grit size (29 μm), 600 grit size (9 μm) and 1200 grit size (3 μm) were used. The incorporation of weight fraction of SiC ranges from 2.5 %, 5 %, 7.5 % and 10 %. The microstructures of the produced composites were examined using a scanning electron microscope. Mechanical properties were determined by using a universal testing machine of 30 KN load. Microhardness was performed on the composite specimens by using a LECO 700 HT tester with a load of 492.3 N and with a dwell time of 10 seconds. The electrical properties were determined using a Keithley instrument Model 2400 point probe machine. The results show that the modulus, yield strength and hardness of the composite increase at lower grit sizes of silicon carbide of 3 micron. The maximum hardness of 26.1 HVN and maximum modulus elasticity of 1517.6 N/mm −2 was obtained O. S. I. Fayomi at 7.5 % weight fraction of SiC. A boost in the mechanical and electrical properties of the produced alloys was gained by changing the grit size of the silicon carbide.
