Abstract Metal matrix composites (MMCs) are lightweight, hard materials applied in heavy-duty applications such as automobile, aerospace, and electronics, well sports equipment. MMCs reveal exceptional physical mechanical properties, including high strength, corrosion, wear resistance, higher stiffness, toughness. However, owing to poor surface finish, accelerated tool wear, material removal co...

Composite material is a combination of two or more materials having compositional variations and depicting properties distinctively different from those of the individual materials of the composite. A composite mixture having more than one fiber is known as hybrid composite During the past decade, considerable research effort has been directed towards the development of in situ Metal Matrices h...

Composite material in general, and metal matrix composites in particular, have been a main topic in research for the last 15 years. Metal matrix composites (MMC) have been found to be useful in a number of engineering applications and particle reinforced aluminum MMCs have received considerable attention due to their excellent engineering properties like high strengt h to weight ratio, high tou...

Nickel in elemental form or alloyed with other metals or materials has made significant contribution to our present day society. Nickel and nickel alloys are the class of advanced material that are are identified as candidate materials for marine applications and vitally important to aerospace, automotive industries because of their ability to withstand a wide variety of severe operating condit...

Metal matrix composites (MMCs) are now gaining their usage in aerospace, automotive and biomedical industries because of their inherent properties like high strength to weight ratio, low wear rate etc. To machine these types of materials conventional machining methods are unsuitable because of high tool wear and tooling cost. Electro discharge Machining (EDM) is one of the important nontraditio...

Article history: Received: 27.6.2013. Received in revised form: 14.11.2013. Accepted: 19.11.2013. Aluminum based Metal Matrix Composites (AlMMC) have been found in different industrial applications due to their excellent properties compared to conventional materials. Machining of these composites is difficult due to their hard particle reinforcements. The wider usage of these composites is limi...

In this presentation, frst, the Internal Damping (I.D.) phenomena and related theories that have been previously reported in the literature for Metal Matrix Composites (M.M.C.s) are reviewed briefly. Then, the paper is focused on the transient ID phenomena. Especially, it is shown that a broad Iow temperature peak appears in the low frequency internal damping (ID) spectra of aluminium based mic...

This paper deals with metal matrix composites (MMCs) of Al 7075 alloy containing different weight percentage (2.5, 5, 7.5, and 10) basalt short fiber reinforcement and unreinforced matrix alloy. The samples were produced by the permanent stir casting technique. The casting ingots were cut into blanks to be forged in single stage and double stage, using MN press and graphite-based lubricant. The...

Metal matrix composites (MMCs) have superior mechanical strength and wear resistance as compared to base alloy. Aluminium matrix reinforced with low density discontinuous particulate composites has good potential in automobile and aerospace applications. The main challenge is to produce the light weight composite in a cost effective way to achieve the greater properties. In the present study, a...
