Metal matrix composites (MMCs) have been developed in response to the enormous demand for special industrial materials and structures automotive aerospace applications, wherein both high-strength light weight are simultaneously required. The most common, inexpensive route fabricate MMCs or metal nanocomposites (MMNCs) is based on casting, reinforcements like nanoceramics, -carbides, -nitrides, ...

Herein, it is concerned with the use of profilometry-based indentation plastometry (PIP) to obtain mechanical property information for particulate metal matrix composites (MMCs). This type test, together conventional uniaxial testing, has been applied four different MMCs (produced various contents and processing conditions). It shown that reliable stress–strain curves can be obtained using PIP,...

Magnesium is among the lightest structural metals available, with capacity to replace traditional alloys in mass-saving applications while still providing increased stiffness and strength. The inclusion of reinforcing components into metallic matrix has a substantial impact on stiffness, specific strength, wear behaviour, damping creep properties when compared typical engineering materials. Due...

In this preliminary study, a set of self-lubricating copper-tungsten disulfide (Cu-WS2) composites are prepared via powder metallurgy route to analyze the effects solid lubricant concentration on their tribological, electrical and wettability properties. An extensive characterization is performed preliminarily assess potential application these metal matrix (MMCs) in sliding contacts working un...

Machining of metal matrix composites (MMCs) has now become an essential task in shaping them to their final usable forms for various industrial applications. These machining operations may range from drilling simple through holes cutting and the into complex shapes. Determination optimal process parameters during presents a combinatorial optimization problem, which turn out be more due involvem...

Abstract To explore the influence of path deflection on crack propagation, a planning algorithm is presented to calculate growth length. The fatigue life metal matrix composites (MMCs) estimated based an improved Paris formula. Considering different expansion coefficient materials, unequal shrinkage will lead residual stress when composite molded and cooled. model by modified ratio stress. Dijk...

This paper studies the surface finish and integrity of glass, silicon, some advanced ceramics and aluminum-based metal matrix composites (MMCs) reinforced with ceramic particles, precision machined by various machining processes. The studies revealed that grinding/lapping operations using inexpensive machine tools can produce ductile streaks on glass and silicon surfaces under good grinding/lap...
