The investigations of magnesium based matrix material reinforced with the TiO 2 particles with various weight ratios of 2.5, 5, 7.5 and 10% are presented in this research paper. The purpose of this work is to elaborate the manufacturing processes of pure magnesium with the addition of Titanium oxide through the powder metallurgy route. The powder blending was done with the energetic ball and jar mill. The compaction pressure of 650Mpa is given to improve cold compaction. The Sintering temperature of 550 o C and holding time of 30 min was used to sinter the compacts to get better results. The microstructural analysis by scanning electron microscopy (SEM) for the starting powders and fabricated samples are carried out for the investigation. The mechanical properties are evaluated and the results proved that improvement in 13.8% ,17.8% and 29% for the density, hardness values and universal tensile strength. Keywords: Magnesium, Titanium oxide, SEM analysis, Mechanical properties, Powder metallurgy. I.INTRODUCTION Composite materials could be in the form of natural or synthetic which combines two or more chemically distinct materials in order to achieve improved properties over the individual materials. Usually matrix is a ductile or tough material and reinforcing materials are strong with various properties and in the form of particles, platelets, whiskers, short fibers, and continuously aligned fibers are combined together to get desired properties, otherwise that was not available in any single conventional material. The incorporation of reinforcement increases stiffness, specific strength, design flexibility, corrosion resistance, fracture resistance, durability and reducing relative investment. The advanced composites are used in aerospace, sporting goods, military and commercial aircraft, etc. magnesium based composites used in space and satellite structures, Antenna structures, Helicopter transmission structures with the reinforcing particles of Graphite, boron, alumina respectively. The composites can be used in thermal management and support systems for electronic packages like integrated circuit materials. Magnesium is useful in manufacturing of electronic devices such as cameras, laptops and mobile phones [1][2][3]. It is well known that the elastic properties of metal matrix composites are strongly influenced by micro structural parameters of the reinforcement such as shape, size, orientation, distribution and volume fraction [4]. The mechanical properties of composites are controlled by the structure and properties of the reinforcements [5]. There are several metal matrix processing technologies available in modern world era. The powder metallurgy process followed by hot extrusion and casting methods is playing vital roles among them. The major advantage of powder metallurgy over other methods is that small elements with near net shape could be manufactured with dimensional stability, whereas manufacturing of locally reinforced elements from composite materials with excellent surface quality s...
