“…Low stirring speed cause agglomeration of fibers at some regions and uniform distribution of reinforcement throughout the matrix can be ach-ieved by increasing stirrer speed above 600 min À 1 . Similar results have been observed in other studies [15,[35][36][37][38] that high stirring speed promotes uniform dispersion of reinforcement in matrix. The variation of pouring temperature and stirring speed with hardness of composites showed that increase in pouring temperature increases the hardness of composites up to 750°C, Figure 7.…”

Copper coated steel fibers reinforced LM13 aluminum alloy composites have been prepared using stir casting process. Experiments have been designed using response surface methodology (RSM) by varying wt % of reinforcement (0–10), stirrer speed (350 min−1–800 min−1) and pouring temperature (700 °C–800 °C). Microstructure and hardness of composites have been investigated. Analysis of variance, significance test and confirmation tests have been performed and regressions model has been developed to predict the hardness of composites. Response surface plots reveal that hardness of composites increases with increasing wt % of reinforcement and stirrer speed. The optimum stir cast process parameters for obtaining higher hardness are found to be the wt % of reinforcement of 8.2, pouring temperature of 748 °C and stirrer speed of 708 min−1.

Aluminium is one of the most common metals in the world and its use is increasing day by day in many industries mostly in space industry and automobile industry because of its light weight and high strength capabilities. Aluminium-based alloys have great potential for cost saving application due to their light weight combine with high specific strength and corrosion resistance, as well as good castability. This paper mainly emphasis with the fabrication of Aluminium composites with SiC particles and jute ash particles. Hardness and tensile properties of the prepared Aluminium composite were determined before and after addition of SiC and Jute Ash particulates to find the extent in improvement of properties. SEM images have shown the grain boundaries formation. Results shows that the tensile strength is maximum in case of composite with SiC with value of 123MPA when compared to unreinforced 6061Al matrix with strength of 64MPa.

“…Titanium carbide (TiC) is a hard refractory ceramic material with FCC crystal structures. The Young's modulus is approximately 400 GPa and the shear modulus is 188 GPa for the TiC, 109,110 which is a good candidate as reinforcement for improving stiffness of aluminum alloys 111,112 . Al/TiC in-situ composites can be synthesized by several techniques, including: (a) the reaction of K 2 TiF 6 salt and graphite, (b) the direct reaction of Ti and C powders, (c) the addition of Al-Ti-C powder into the Al melt, and (d) the reaction of CH 4 gas with the Al-Ti melt.…”

The Young's modulus of aluminum-based materials is one of the most important mechanical properties in controlling structural performance. The improvement of the Young's modulus of castable aluminum-based materials is essential for improving their competiveness in light weighting structural applications. Currently, there are limited options for cast aluminum alloys with outstanding Young's modulus. Also, for further stiffness improvement and thereby weight lightening, in-depth understanding of the relevant mechanisms for modulus improvement in aluminum alloys is necessary. This review focuses on the Young's modulus of cast aluminum-based composites, as well as aluminum alloys reinforced with continuous metallic fibers (bimetallic materials). The effect of different chemical elements in cast alloys, the constituents of in-situ and ex-situ formed aluminum matrix composites, and the wire-enhanced bimetallic materials on the Young's modulus of aluminum-based materials are reviewed. The Young's modulus of cast aluminum alloys can be improved by: (a) introducing high modulus reinforcement phasessuch as TiB 2 , SiC, B 4 C, and Al 2 O 3into aluminum by in-situ reactions or by ex-situ additions; and (b) forming bimetallic materials with metallic wire/bar reinforcement in the aluminum matrix. The performance of a stiff aluminum alloy depends on the volume fraction, size, and distribution of the high modulus phases as well as the interface between reinforcement and Al matrix. One of the major concerns is the reduction of the ductility of castings after adding specific high modulus phases to increase the Young's modulus. Further research into the improvement of Young's modulus and the ductility of aluminum alloys is necessary through proper selection of reinforcement, optimizing interface, and distribution of reinforcement.
