Abstract:

 This article demonstrates how different cooling rates and precipitation hardening affected the mechanical properties of AA2024. Three impact test samples were chosen. Solution heat treatment was conducted at 500 °C for 2 hrs., followed by quenching in three different quenching media (Sunflower Oil, Sesame Oil, and Corn Oil). As a result, the Sunflower Oil showed the lowest shock absorption rate; hence, it was chosen as the quenching medium for this study. Consequently, all samples of tensile, hardness, and impact tests were solution heat treated at 500 °C for 2 hours, then quenched in Sunflower Oil to room temperature and artificially aged at temperatures of 180°C for 1,2,4 hour, 195°C for 1, 2, 4 hour, and 210°C for 1,2,4 hour. Considerable improvements in strength and hardness were observed while decreasing the ductility Due to the production of finely dispersed grains. Precipitation hardening at 180°C for 1 hour was the overall optimum achievement, which enhanced the UTS by 28.7% to 579 MPa, compared to the as-received sample with UTS 450 MPa. While annealing has reduced the UTS by 32.7% to 303 MPa.
