developments in the non traditional machining of particle reinforced Metal Matrix Composites
International Journal of Machine Tools & Manufacture, 2014Co-Authors: Aniket PramanikAbstract:Abstract The non-traditional machining of particulate reinforced Metal Matrix Composites is relatively new. However, researchers seem to pay more attention in this field recently as the traditional machining of particulate reinforced Metal Matrix Composites is very complex. This research investigates different non-traditional machining, such as electro-discharge, laser beam, abrasive water jet, electro-chemical and electro-chemical discharge machining of this composite materials. The machining mechanism, material removal rate/machining speed and surface finish have been analysed for every machining process. This analysis clearly shows that vaporisation, melting, chemical dissolution and mechanical erosion are the main material removal mechanisms during non-traditional machining. The thermal degradation and the presence of reinforcement particles mainly damage the machined surface. The understanding of electro-discharge, laser beam and abrasive water jet machining is more developed than that of electro-chemical and electro-chemical discharge machining for particulate reinforced MMC.

Fabrication of Nano-Particle Reinforced Metal Matrix Composites
Advanced Materials Research, 2013Co-Authors: Aniket Pramanik, Guy LittlefairAbstract:Nanoparticle reinforced Metal Matrix possess much better mechanical properties over microparticle reinforced Metal Matrix Composites as well as corresponding monolithic Matrix materials. However, the fabrication methods of nanoparticle reinforced Metal Matrix Composites are complex and expensive. This paper investigates and discusses the mechanisms of all the fabrication process, such as powder Metallurgy, liquid Metallurgy, compocasting and hybrid methods, available in the literature. This gives an insight on challenges associated with different processes and ways to improve the fabrication processes. It is found that modified traditional fabrication processes are mainly applied for these materials. The main problem is to achieve reasonably uniform distribution of nanoparticle reinforcement in the methods other than mechanical alloying when the volume or weight percent of reinforcement is higher (> 1%). © (2013) Trans Tech Publications, Switzerland.

basics of Metal Matrix Composites
2006Co-Authors: K U KainerAbstract:Metal composite materials have found application in many areas of daily life for quite some time. Often it is not realized that the application makes use of composite materials. These materials are produced in situ from the conventional production and processing of Metals. Here, the Dalmatian sword with its meander structure, which results from welding two types of steel by repeated forging, can be mentioned. Materials like cast iron with graphite or steel with a high carbide content, as well as tungsten carbides, consisting of carbides and Metallic binders, also belong to this group of composite materials. For many researchers the term Metal Matrix Composites is often equated with the term light Metal Matrix Composites (MMCs). Substantial progress in the development of light Metal Matrix Composites has been achieved in recent decades, so that they could be introduced into the most important applications. In traffic engineering, especially in the automotive industry, MMCs have been used commercially in fiber reinforced pistons and aluminum crank cases with strengthened cylinder surfaces as well as particle-strengthened brake disks. These innovative materials open up unlimited possibilities for modern material science and development; the characteristics of MMCs can be designed into the material, custom-made, dependent on the application. From this potential, Metal Matrix Composites fulfill all the desired conceptions of the designer. This material group becomes interesting for use as constructional and functional materials, if the property profile of conventional materials either does not reach the increased standards of specific demands, or is the solution of the problem. However, the technology of MMCs is in competition with other modern material technologies, for example powder Metallurgy. The advantages of the composite materials are only realized when there is a reasonable cost – performance relationship in the component production. The use of a composite material is obligatory if a special property profile can only be achieved by application of these materials. The possibility of combining various material systems (Metal – ceramic – nonMetal) gives the opportunity for unlimited variation. The properties of these new 1

Machining of Aluminium Metal Matrix Composites with Electrical Discharge Machining - A Review
Materials Today: Proceedings, 2015Co-Authors: Bhaskar Chandra Kandpal, Jatinder Kumar, Hari SinghAbstract:Electrical discharge machining (EDM) is the process of machining electrically conductive materials by using precisely controlled sparks that occur between an electrode and a workpiece in the presence of a dielectric fluid. Now a day's EDM process is commonly used for machining of Metal Matrix Composites which have vast applications in automobile, aircraft, and railway sectors. Aluminium Metal Matrix Composites are one of the important types of MMC because of their advanced properties like highest strength and light weight. Development of these lightweight materials has provided the automotive industry with numerous possibilities for vehicle weight reduction. In this paper we have discussed about EDM process, its parameters and role of EDM process in machining of aluminium based Metal Matrix composite materials (AMMC). The current research work going in this field was also discussed in this paper.

Fabrication of Aluminium Metal Matrix Composites with Particulate Reinforcement: A Review
Materials Today: Proceedings, 2017Co-Authors: C. S. Jawalkar, Ajay Singh Verma, N. M. SuriAbstract:This paper presents a summary of work reported on Aluminium Metal Matrix Composites with particulate reinforcement. Aluminium Metal Matrix has growing demand in aircraft, automotive and other industries due to its light weight, high strength to weight ratio, corrosion resistance and workability. Particle reinforced aluminium Matrix Composites are preferable due to their reduced cost, uniform properties, and their ability to be like monolithic materials. Although numerous method are available to fabricate the particulate Metal Matrix composite, stir casting is the most preferable one due to its cost effectiveness and convenience. Present paper reviews the problems taken and results obtained by various authors who have contributed in the area of Aluminium Metal Matrix Composites with particulate reinforcement through stir casting. The reported works reveal that decrease in particle size and increase in percentage addition of reinforcement increase hardness and tensile strength of the composite.

fabrication of Metal Matrix Composites by Metal injection molding a review
Journal of Materials Processing Technology, 2008Co-Authors: Hezhou Ye, H P HongAbstract:Metal injection molding (MIM) is a near net-shape manufacturing technology that is capable of mass production of complex parts cost-effectively. The unique features of the process make it an attractive route for the fabrication of Metal Matrix composite materials. In this paper, the status of the research and development in fabricating Metal Matrix Composites by MIM is reviewed, with a major focus on material systems, fabrication methods, resulting material properties and microstructures. Also, limitations and needs of the technique in composite fabrication are presented in the literature. The full potential of MIM process for fabricating Metal Matrix Composites is yet to be explored.
