“…The ball milling is one of the most suitable techniques for the formation of nanoparticle reinforced composites consisting of fibers, short fibers, particles or whiskers. These composites are mainly used in the aerospace applications due to their enhanced mechanical properties (Sankar and Singh, 1998;Parvin et al, 2008;Dashtbayazi and Shokuhfar, 2007).…”

Purpose -The purpose of this paper is to understand the effect of graphite content on the properties of aluminum alloy/silicon carbide/granite (Al/SiC/Gr) composites. Design/methodology/approach -Hardness and wear tests were applied to the powder metallurgical composites, and microstructural characterization was conducted. Findings -Optimum graphite content for maximum wear resistance is reported as weight 6 per cent. Originality/value -Results of this study may help light weight Al/SiC/Gr composites to be used in different industrial applications.

The influence of flow properties of aluminium alloys (Al -5Si, Al -4Mg,RR58) obtained from aluminium powder is discussed. The constitutive equations relating flow-stress, temperature, density, strain, aspect ratio have been analysed in order to establish structure -property correlations. These response variables have generally been investigated by means of hot compression tests with the help of statistical analysis. In statistical techniques, response surface methodology has been used for this investigation. It is a collection of mathematical and statistical techniques that is useful for the analysis of problems in which the response is influenced by several variables. A mathematical model has been developed to compute the flow stress which combines the above mentioned process parameters. The main and interaction effects of the process parameters have also been studied using ANOVA techniques. The proposed mathematical model has been validated by the experimental results available from earlier investigations. The proposed model can be applied to predict the magnitude of flow stress during metal working of aluminium alloys. The results show that flow stress is more sensitive to strain and temperature than to other parameters.

“…The Al matrix nanocomposite can be produced by two different approaches: (i) direct mixing of nanosize Al 2 O 3 particles, or (ii) displacement reaction during ball milling of aluminium with a suitable oxide [17]. Although direct mixing of nanoparticles is an easy approach to produce aluminium matrix nanocomposites, expensive starting materials and a heterogeneous microstructure can be the two major drawbacks of this technique [18]: mechanical alloying is generally more successful in achieving the fine distribution of ceramic nanoparticles [19]. This technique, which is usually employed in powder metallurgy, is well known in the fabrication of composites using mechanochemical synthesis [20, 21].…”

In this Letter, Al-SiC-Al 2 O 3 metal matrix nanocomposite powder was successfully synthesised employing a mechanical alloying technique, through a mechanochemical reaction among aluminium (Al), silicon dioxide (SiO 2) and carbon (C). For commercial purposes, the materials (Al, SiO 2 and C powders) and also the method of synthesis (mechanical alloying) is considered to be cost-effective for production of Al-SiC-Al 2 O 3 nanocomposite. The structural evaluation of powder particles after different milling times was conducted by X-ray diffractometry, and scanning electron microscopy. The results showed that during ball milling Al, SiO 2 and C reacted through a mechanochemical reaction producing Al-SiC-Al 2 O 3 metal matrix nanocomposite powder after 50 h of ball milling and annealing at a temperature of 650°C for 1 h. The crystallite sizes of phases remained in nanometric scale.
