Stirring was done to get uniform dispersal of reinforcement particulates in the matrix material. For the fabrication of a composite the aluminium (Al 7075) alloy used as matrix material and the titanium carbide particulates were used as reinforcements. The particulates having an average size 20 micrometer (μm). The reinforcement TiC particles were introduced in the matrix with different weight percentages 3%, 5%, 7% and 9%. Then the tensile strength, yield strength, percentage of elongation and hardness properties of the produced composites specimen studied. The tensile strength and yield strength increased with increasing reinforcement weight percentage. The percentage of elongation decreases with increasing reinforcement particles. As the wt% of reinforcement (TiC) increases the Vicker, s hardness of composite material increased and it is more than the base material. The 7% wt of reinforcement grant better properties. All the composite specimens shows the satisfactory mechanical properties. Keywords: Metal matrix composites, titanium carbide, stir casting. 1. INTRODUCTION Traditional Inflexible materials own the restrictions to attain healthy amalgamation of strength, toughness, stiffness and density. To conquer these defects and to congregate the composites are most hopeful materials of modern importance. Metal matrix composites have outstandingly advanced properties incorporating high peculiar strength, specific modulus, damping capacity and better wear resistance matching with without reinforced alloys. Metal matrix composites (MMCs) drops in category of outstanding engineering in forth coming era for automotive, defense, constructional, thermal and electronic and wear application foundation on calibration work. At the present time appliance of metal matrix composites material has regard as in a lot of day by day life bring into plays and even this might for petite time utilize. There are two types common methods are there for the AMMCs, namely casting method and powder metallurgy method. Finally proved that the casting method was gave the improved better mechanical properties than the powder metallurgy method for the aluminium metal matrix composites with reinforcements. In the preparation of Al 7075 – TiC composites stir casting procedures effectively implemented[1]. The aluminium metal matrix composites (AMCs) the reinforcement elements are usually emphasized in the matrix in volume fraction lower than 30% for used to constructional & wear opposition purposes. AMCs are fabricated by either by powder metallurgy process or by stir casting methods. AMCs are less expensive comparing to the uninterrupted fibers AMCs [2]. The improvement of a appropriate high strength metal matrix composite in relation with study of new material improvement, and in addition to find its mechanical properties. It was found that the deviation of the tensile potential of the composite improved by 50 percent from 10 to 15 weight percentage. This aspect be also make easy by the good bond among the metal and matrix and as a result the composite damage at that vital length happen to be rare, thus rising the potency of the composite and deliver the deviation in stress allocation of the composite [3]. The hardness of composite material increased as the incorporation of reinforcement in the metal matrix goes on increased based on the strength of the composite material the mechanical properties were viewed, so that it proves that the mechanical properties were controlled by the structural and reinforcement incorporated it that composites. It also verified that if the hard ceramic reinforcement particles adding increases the composite density also increases [4]. Hence in this paper attempts is made to produce Al matrix composites with varying weight percentage of 3%wt, 5%wt, 7%wt and 9%wt reinforcement particles of TiC and to assess the mechanical properties. 2.
