The high cost of fabrication hindered the actual application of metal matrix composite (MMC) despite of their high stiffness, strength, corrosion resistance, wear resistance, non-reactivity with chemicals and so many other tailored quality which are never obtained in alloy of metals. In this study, a modest attempt has been made to find out the process parameters at which best mechanical proper...

A TIG surface alloying process was applied to modify the of ductile cast iron samples. Using this process, in-situ metal matrix composite (MMC) layers were produced on samples improve their wear resistance. These made by melting substrates and powders as additional material into melt pool. The efficiency preheating prevent cold cracks during solidification verified. Moreover, a buffer layer in ...

Aerospace engine and airframe designers are constantly seeking lighter weight high strength materials to reduce weight and improve performance of powerplants and aircraft. Titanium metal matrix composites (Ti MMCs) have offered the promise of significant weight savings since their initial development in the early 1960s but until recently, their inadequate quality and reproducibility combined wi...

Abstract This research article aims to produce a metal matrix composite (MMC) material consisting of Cu-20%TiC using the powder metallurgy route, followed by sintering. The study provides insight into impact different TiC particle sizes on physical, mechanical, and wear properties MMC. surface morphology samples was analyzed scanning electron microscopy, while Vickers hardness tensile tests wer...

This work reports the influence of alumina fiber reinforcement an AZ91Nd MMC (metal matrix composite) on PEO coating formation process in a sodium phosphate-based electrolyte. By comparison with pure AZ91Nd, evolution during processing and characteristics resultant were investigated. The voltage response as function time was changed. Lower presence is responsible for lower thickness. morphology...

The macroscopic load-bearing capability of a composite is directly related to the strain partitioning due to load transfer between the component phases. Using neutron diffraction, the elastic mean phase strains were measured during in-situ loading of a Cu-15 vol pct Mo particulatemetal-matrix composite (MMC) at 25 8C, 300 8C, and 350 8C. The degree of load sharing at each temperature was compar...

Abstract In the present work, it’s required to obtained wear rate effectors’ values of A356 Al-Si/Al 2 O 3 composite (Al wt%, applied load, hardness, and sliding distance) obtain a certain specific rate. So, behavior cast heat-treated metal matrix composites (MMC) were investigated as function its effectors. Five weight fractions Al particles used produce specimens using stir casting. Two diffe...

Metal matrix composites (MMCs) are among the very important engineering materials by which the combinations of various properties can be achieved. The MMCs have the great potential for use in automobile and aerospace industries for possessing high strength, stiffness and hardness. The reinforcement types used in the composites are continuous, discontinuous, short, whiskers and particles. The at...
