Metal matrix composite (MMC) is engineered combination of the metal (matrix) and hard particle (reinforcement) to get tailored properties. MMCs are either in use or prototyping for the space shuttle, commercial airliners, electronic substrates, automobiles, golf clubs, and a variety of other applications.In this study, carbon nanotubes (CNTs) reinforced aluminum MMCs were synthesized by DPDS fo...

metal matrix composites have been widely used in industries, especially aerospace industries, due to their excellent engineering properties. however, it is difficult to machine them because of the hardness and abrasive nature of reinforcement elements like silicon carbide particles (sicp).in the present study, an attempt has been made to investigate the influence of spindle speed (n), feed rate...

gears are one of the most critical components in power transmission system of an automobile and also many rotating machinery. many studies have been conducted on optimum gear design. the main objective is to design different aluminium metal matrix composite spur gears before and after optimization. aluminium metal matrix material composites are preferred mostly due to their low density. also th...

X-ray computed tomography (CT) techniques have been used to evaluate a structural index of high performance metal matrix composites (MMC). Beside of classical features like the determination of number of fibres and eccentricity of fibre bundles an order parameter can be defined and demonstrated for the SiC fibre arrangement in Ti-MMC, which can be used to assess these materials. The samples for...

In view of large interest in the improve of Al/Al alloy based Metal matrix Composite and high-temperature ceramics on the base of silicon carbide, a comprehensive review of the data on structure, properties and the known methods of processing of silicon carbide seems timely. The most striking feature of silicon carbide is its polytypism, i.e. formation of a great number of structural changes wi...

The effect of molybdenum (Mo) on the microstructure and creep behavior of nominally Ti–24Al– 17Nb (at.%) alloys and their continuously reinforced SiCfiber composites (fiber volume fraction = 0.35) was investigated. Constant-load, tensile-creep experiments were performed in the stress range of 10–275 MPa at 650 C in air. A Ti–24Al–17Nb–2.3Mo (at.%) alloy exhibited significantly greater creep res...

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...

Microstructural aspects of composites such as particle size, shape, and distribution play important roles in deformation behavior. 3D visualization of porosity and Fe-rich inclusions in three dimensions is critical to a thorough understanding of fatigue resistance of metal matrix composites (MMC) because cracks often initiate at these defects. In this paper we have used X-ray synchrotron tomogr...
