This document describes an experimental analysis that was conducted on aluminum alloy 6063 reinforced with silicon carbide particles. The study aimed to evaluate the microstructure, mechanical properties, and compare aluminum 6063 with steel at different weight percentages of silicon carbide (2%, 4%, 6%, 8%, 10%). The aluminum-silicon carbide composites were produced using stir casting, where silicon carbide particles were added to molten aluminum alloy and mechanically mixed. Tests were performed to analyze the hardness, tensile strength, and wear resistance of the composites compared to steel. The results indicated that adding silicon carbide particles improved the mechanical properties of the aluminum composite material.

Corrosion Characterization of Aluminium 356 Hybrid Composites in Neutral Chlo...ijtsrd
Hybrid composites are the composites which contain two different reinforcements in them. One of the reinforcements will be added in different quantities and another one will be added with same quantity. In this work hybrid composites of aluminium 356 are manufactured by adding fly ash and silicon carbide particulates. Composites are manufactured by liquid melt metallurgy technique using vortex method. Composites containing 2% fly ash and 2, 4 and 6 weight percentages of SiC particulates were manufactured. Matrix alloy was also casted in the same way for comparison. Static weight loss corrosion test and potentiodynamic polarization tests were conducted in different concentrated solutions of neutral chloride like sodium chloride. In both the tests the hybrid composites exhibited decreased corrosion rate with increase in reinforcement content. Hence hybrid composites are more suitable than the matrix alloy for applications. V.

Characterization of Al/WC/Fly ash Metal Matrix Compositesijtsrd
Metal matrix composites are formed by combination of two or more materials (at least one of the materials is metal) having dissimilar characteristics. In this present investigation, aluminium (Al 6061) as base matrix metal and tungsten carbide (WC) particulate, fly ash as reinforcements. Fabrication of MMCs was done by stir-casting process. The Tungsten Carbide particulate was added in proportions of 1%, 2%, and 3% and Fly ash was added in proportions of 2%, 4%, and 6% on mass fraction basis to the molten metal. The different combination sets of composites were prepared. Mechanical properties like tensile strength and hardness were studied for both reinforced and unreinforced Al 6061 samples. Microstructure examination was carried by using Scanning Electron Microscope (SEM) to obtain the distribution of tungsten carbide particulate and fly ash in base matrix. From the results, it was found that the tensile strength and the hardness of the prepared metal matrix composites increased with increase in tungsten carbide and fly ash content. The Scanning Electron Micrographs of the samples indicated uniform distribution of tungsten carbide and fly ash particles in the base matrix without voids before testing and with voids after testing.

Effect of silicon carbide percentage on fracture toughness of aluminium silio...eSAT Journals
Abstract Metal matrix composites are composites in which one component will be a metal and other metal or non metal. It has wide applications in various fields like automobile, turbines blades etc which needs good mechanical properties. This thesis work studies about Aluminium Silicon Carbide metal matrix composites and their properties. Earlier studies revealed that as the percentage of Silicon Carbide is increased the properties get increased up to a limit and fracture toughness gets reduced beyond that. Here, in this work different percentage of SiC is added and fracture toughness is analyzed in terms of Stress intensity factor since fracture toughness cannot be calculated directly. Both software simulation and experimental methods has been done to find out the best percentage composition. Keywords: Metal matrix composites, Aluminium Silicon Carbide, Fracture Toughness, Stress Intensity Factor
Evolution of automobile production has been driven by competitive materials. Light-weight alloys are
continuously developed as most sustainable for automotive sector. Aluminum is being used as a successful
material in automotive applications due to its low weight, higher strength, good corrosion resistance and
formability to suit different design requirements. Since aluminium has the potential to be used as replacement
of the current automotive materials like steel and cast iron, its demand has increased greatly. In a further
development aluminium metal matrix composites (MMCs) were developed and these have improved wear
resistance, high fatigue strength and better thermal stability, as compared with those of aluminum. In
automobile sector, wear is a major problem, specifically in engineering assemblies and materials used for this
purpose should have good tribological properties. To this effect Al MMCs have attracted significant attraction
since they have improved wear resistance. Metal matrix composites are usually produced with secondary
particles in the form of either continuous or discontinuous fiber or particles. From the viewpoint of good
mechanical properties aluminium matrix is generally reinforced by oxide or carbide, nitride or boride
ceramics (like Al2O3, SiC, Si3N4, TiC, TiB2. Reinforcement of the matrix with only one of these
reinforcements may not yield desired properties and the matrix may need to be augmented with other
reinforcements also. Graphite and SiC are the reinforcements used widely in automotive industries to achieve
better mechanical and tribological properties and dampen the vibrations with less operational costs.
Aluminum metal matrix composite can be produced by various methods including powder metallurgy,
conventional casting technology, etc. Among the casting methods semisolid processing of composites yields
better mechanical strength. This review deals with various manufacturing methods of metal matrix composites
processing and insight on semisolid processing and its process parameters.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
