Abstract: Aluminium Al 2024 alloy is widely applied in various Industries in automobile and aerospace sectors. This study reveals the effect of microstructure and mechanical properties with impact on heat treatment and aging process. Mechanical tests were conducted to study the behaviour of Al reinforced 2024 matrix composite produced through squeeze cast technique and heat treated to T6 Heat treatment process. Aluminum ingots were melted in a furnace and poured into mould cavity of 25mm diameter. Squeeze casted composites were heat treated as per ASTM standards, at a temperature of 525°C for 12 hours followed by a temperature of 300ºC for 8 hours. In order to examine the effect of heat treatment and aging processes microstructure and mechanical properties such as hardness, tensile strength were analysed in as-cast condition and after heat treatment and aging process. The properties were enhanced for the aged composites compared to as cast condition.
Keywords: Aluminium 2024 alloy, Squeeze casting, microstructure, tensile strength, heat treatment & aging.
