Fine mechanical and thermal properties of metal matrix composites make them more demanding in various fields such as automotive, aerospace and structural applications. In this paper an effort has been made to fabricate a metal matrix composite, Titanium-di-oxide and silicon carbide reinforced in Al 6061 matrix using stir casting method. The reinforcements were added in 2%, 4% and 6% of weight to Al6061 to fabricate the metal matrix composite. Castings were machined and the specimens were prepared for various testing. Mechanical properties such as tensile strength, hardness, and corrosion analysis were studied for various compositions of reinforcements. And then the reinforcement was analyzed and studied for the improvement of mechanical properties in the material.

In this experiment, comparison analysis of mechanical properties, porosity and grain size of Pure Al (powder), 95%AL + 5% B4C (With sand casting method) and 95%AL + 5% B4C (With ECAP method) are determined. The ECAP method value is much greater than the sand casting method,because of metal matrix composite microstructure refinement during the pressing operation. Because of material porosity value decreases, powder particle consolidation, the closure of porosity, grain refinement and improve in dislocation occurs as ECAP method gives the results of Mechanical properties as like tensile strength 105.8Mpa, Hardness 94HV, density 888.88kg/m3values increase. At the same time, porosity and grain size value will be reduced because of individual power consolidation happening during ECAP methods like as 1.63% and 8μm. In this metal matrix composite is applied to aeronautical and automobile industry

Aluminium based composite are getting a vast scope nowadays because of its properties and availability. In the present work, fly ash and AL2O3 reinforced composite are prepared using stir casting technique for varying wt.% (fly ash 3% and AL2O3 3%, 6% & 9%). Hardness and tensile properties were determined, with the addition of reinforcement the properties are improved compared to the parent metal alone. Based on the evaluation 6% AL2O3 and 3%fly ash gives a better result as compared to other composition.

Aluminium alloys are widely used in aerospace and automobile industries due to high strength to low weight ratio and their good mechanical properties such as better corrosion resistance and wear resistance, low thermal expansion as compared with other metals. The main objective of our work is to improve the mechanical properties such as impact strength, hardness of Aluminium based Metal Matrix Composite (MMC), and its relation with processing of the silicon carbide particulate (SiCp) as reinforced in Aluminum matrix. AA6061 alloy is chosen as matrix alloy, in which Aluminum is the base element. The work has been proposed for four different weight proportions of SiCp to aluminium matrix and the processing of the metal matrix composite is to be processed with stir casting setup and heat treated.

Electromagnetic Stir Casting

The AA2014/5 wt. % carbonized eggshells metal matrix composite used in this study was fabricated by electromagnetic stir casting technique and immediately extruded on universal testing machine at 60 MPa using cylindrical H13 tool steel die coated with graphite to avoid upper flow of eggshells particles and to improve wettability of eggshells with AA2014 alloy. Microstructures of composites show some agglomerations in non-extruded samples while uniform distribution of carbonized eggshell particles. Optimum combination of precipitation hardening parameters achieved using response surface methodology to further improve the properties of AA2014/5 wt. % eggshell composites. Optimum values of solutionizing time, aging temperature and aging time were found to be 4.5 h, 250℃ and 13.5 h, respectively. More grain refinement of extruded AA2014/5 wt. % eggshell composites were observed after heat treatment at optimum precipitation hardening parameters. After heat treatment, fractographs of the AA2014/5 wt. % eggshells composite showed that fracture is dominated by trans-granular type. Density of the AA2014 is 5% higher than AA2014/5 wt. % eggshells metal matrix composite. It is observed that mechanical properties improve when carbonized eggshell particles are reinforced in matrix AA2014 aluminium alloy. After the heat treatment at optimum precipitation hardening parameters, mechanical properties are further improved.
