Abstract:
Aluminium (Al) alloy 6061 is one of the most extensively used of the 6000 series. Among the various useful alloys, aluminium alloy 6061 is typically characterized by properties such as fluidity, cast ability, corrosion resistance and high strength-weight ratio. Aluminium-based alloy MMCs has received increasing attention in recent decades as engineering applications. This alloy has been commonly used as a base metal for MMCs reinforced with a variety of fibres, particles and whiskers. Tungsten carbide (Wc) is approximately two times stiffer than steel, with a Young's modulus of approximately 550GPa, and is much denser than steel or titanium. Powder metallurgy is the process of blending fine powdered materials, compacting the same into a desired shape or form inside a mould followed by heating of the compacted powder in a controlled atmosphere, referred to as sintering to facilitate the formation of bonding of the powder particles to form the final part. Sintering is the process of forming a solid mass of material by heat and/or pressure without melting it to the point of liquification. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the boundaries of the particles, fusing the particles together and creating one new solid piece. The Al-Wc MMC compacts are produced by using sintering furnace which is forwarded by the mixing of Al-Wc powders in V-blender, making of green compacts by hydraulic press. As the wt %of Wc is increased from 0 % to 9% weight as reinforcement in Al matrix, then compressive strength values are improved up to 6% of Wc, after that the compressive strength is gradually decreased at 9% weight of Wc. As increasing the weight percentage of the reinforcement Wc in the matrix, the density values also increased gradually)
