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...

Aluminium metal matrix composites have wide applications in the aerospace and automotive industries due to their excellent physical properties like hardness, tensile strength, etc. The reinforcement of ZrO2 hard ceramic particles soft solid lubricant graphite on AA6082 produces a high-strength composite. This research aims fabricate AA6082-ZrO2-Gr MMCs with different compositions evaluate abras...

ÐMetal matrix composites (MMCs) can be synthesized by aligning metal coated ceramic ®bers in a shaped container and applying pressure at elevated temperatures. The high stresses created at the contacts between neighboring ®bers cause inelastic matrix ̄ow that ®lls inter®ber voids, reduces inter®ber separations and results in composite densi®cation. The rate of densi®cation depends on the contac...

In this research, Al-Ni particle composite strips are formed by accumulative roll bonding (ARB) process using Al strips and Ni powder. The rule of ARB cycles and volume percentage (Vol%) of Ni powder on the microstructure, wear resistance and mechanical properties of the formed composites are investigated. According to the tensile test results, the yield stress and tensile strengths of the Al -...

In this study, the Al/Al2O3-SiC hybrid composite was produced by accumulative roll bonding (ARB). In the first and the second cycles, the particles were uniformly poured between the Al strips during each ARB cycle. In the subsequent cycles, ARB was repeated up to six cycles without adding the particles between the layers. After the total eight cycles, the particles were distributed uniformly wi...

Metal matrix composites (MMCs) have been increasingly used in industries, nuclear plant, and automobiles due to their superior properties compared other alloys, that is owing the tough abrasive hard reinforced particles. It’s complicated machine materials by traditional processes methods, therefore The present study focused on investigation of parameters electrochemical machining (ECM) like ele...

Abstract For metal matrix composites (MMCs), introduction of low-dimensional nano-carbon materials (NCMs) into three dimensional metallic is commonly applied to enhance mechanical and physical properties metals thus significantly extend their wide range applications. However, the interfaces between NCMs are always a major issue for achieving best enhancement effects. In this paper, we investiga...

The dynamic fiber/matrix interface strength for a silicon-carbide-fiber-reinforced, titanium-alloy metal-matrix composite was measured by impacting the end of a fiber extending through a thin specimen with a diamond-tipped projectile at ~2 m/s. The matrix surrounding the distal end of the fiber was supported on the end of a Hopkinson bar fabricated from hypodermic needle tubing, and an interfer...
