In the present research work physical, mechanical and tribological behavior of Aluminum (Al) alloy LM13 reinforced with Nano-sized Titanium Dioxide (TiO2) particulates were fabricated, mechanical and tribological properties were investigated. The amount of nano TiO2 particulates in the composite was added from 0.5% to 2% in 0.5 weight percent (wt %) increments. The Al-LM13-TiO2 Metal Matrix Com...

In this present study, A356.2 Al/Rice hush ash (RHA) metal matrix composites (MMCs) were fabricated by vortex method. Different weight fractions of reinforcement were used to fabricate the composites. Scanning electron microscope equipped with energy dispersive Xray analyzer is used for micro structural characterization. The properties like density, hardness, and ultimate tensile strength were ...

A new severe plastic deformation (SPD) based technique entitled Accumulative channel-die compression bonding (ACCB) is proposed for the fabrication of high strength multi-layered Al/Cu composites for the first time. In order to primarily demonstrate the capabilities of ACCB in the fabrication of metal matrix composites (MMCs), AA 1050 and pure Cu strips were processed. The primary Al/Cu sandwic...

The main focus is material design, combination reinforcement matrix, synthesis principle during process, resulted microstructures as well properties. Thereafter, trend development future forecasted, includin...

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...

Aluminum-based metal matrix composite (MMC) materials are used in the design of ground transportation vehicles and aircraft. Compared with conventional, unreinforced alloys, composite materials usually exhibit higher strength, both at ambient and elevated temperatures, as well as good fatigue strength and wear resistance. MMCs could be produced by variety of methods such as Stir cast, Liquid In...

Silver chloride containing particles of irregular form of the order of 1 ktm in diameter is used as a model material for particle-reinforced metal matrix composites (MMCs). Matrix dislocations due to the mismatch of the coefficients of thermal expansion of the two phases are made visible to transmission optical microscopy through bulk decoration performed at room temperature. The plastic zone a...

Mechanical spectroscopy has been used for studying the relaxation of the mechanical and thermal stresses, which are built at the fibre-matrix interfaces in AICu-A1203 Metal Matrix Composites (MMCs). The interface strength has been evaluated by the stress dependent damping which exhibits a peak of solid friction. This peak is interpreted as due to interface microcracking. Relaxation of thermal s...

The properties of metal matrix composites (MMCs) can be optimized effectively through adjusting the type or the volume fraction of reinforcement. Generally, the coefficient of thermal expansion (CTE) of MMCs can be reduced by increasing the volume fraction of the reinforcement with lower CTE than metal matrix. However, it is great challenge to fabricate low CTE MMCs with low reinforcement volum...
