Investigation of Mechanical Properties and Microstructure of AA2024 and AA7075

Aluminum alloys have been extensively used as structural material due to its high strength and damage-tolerance. Alloy 6061, 2024 and 7075 are engineered to be lightweight and strong,and their ease of formability allows complex shapes and drawn parts,which can then be further enhanced with heat treating. In this study is aimed to improve the mechanical properties of aluminum alloys by heat treatment.AA2024 and AA7075 were selected and each alone at T3 and T6 temper conditions has been studied respectively.For the mechanical properties of AA2024 and AA7075 alloyshardness, fatigue behavior, tensile test and charpy impact test with standard V notched specimens at RTand-5 °C were analysed in the present study. Microstructural characterization has been done using standard metallography.
