Research Topic -Structural Material
The strength of Al alloys are stiffness and strength, Corrosion resistance, High conductivity, Formability, Low-temperature properties, Recyclability. The density of Al is one-third of steel or copper and is lightest available metals. Structural material requiring increased payloads or fuel savings for transport industries use this as a suitable material. Al is a good reflector of radiant energy from ultraviolet to infrared. It has a visible light reflectivity of 80% and hence used in light fixtures and also makes Al ideal as an insulating material to shield against the sun’s rays in summer while insulating against thermal loss during winter. Al is the predominant matrix for the MMCs. The Al-alloys are appealing due to their minimal density, their capability to be enhanced by precipitation, their good corrosion resistance, high thermal, electrical conductivity, and their high damping capacity. Al matrix composites (AMCs) have been comprehensively examined since the 1920s and 18 are now utilized in sporting goods, electronic packaging, and automotive trades. They propose a sizeable variety of mechanical properties reliant on the chemical composition of the Al-matrix. The Al matrix materials in commonplace are Al-Si, Al-Cu, 2xxx, 6xxx and 7xxx alloys. With MMCs, Al-MMCs have favored engineering materials for auto, space, and ore processing trades. These trades require high-performance components that are being used for variabilities of applications due to their high elastic modulus, hardness, tensile strength at room and raised temperatures, wear resistance mutual with extensive mass savings over un-reinforced alloys and excellent thermal conductivity. The benefits of particle-reinforced composites over others are their formability with expense benefit and display improved abrasion resistance. They find applications in parts such as cylinder blocks, pistons, piston insert rings, brake disks, callipers, connecting rod, microwave filters, vibrator component, contactors, impellers, and space constructs. The strength of these composites is relational to the proportion quantity and fineness of reinforced particles. These ceramic particle reinforced Al-alloy composites have directed to a new generation custom made industrial materials with enhanced special properties. Thus the use of Al alloys as a structural material is of importance which needs to be studied.
