dc.description.abstractThis research investigates how the thermal, mechanical, and structural properties of the EN AW-6082 aluminum alloy are affected by aging parameters (temperature and time). To investigate these properties, thermal diffusivity and hardness were measured, and scanning electron and transmission electron microscopes were used to detect structural changes. The heat treatments consisted of solutionizing at 550 °C for an hour and then quenching in ice water, followed by aging at two different temperatures (180 °C and 200 °C) for 1-8 hours. Investigation revealed that the hardness increases gradually with aging time, reaching a maximum of 124 HV 10 after aging at 180 °C for six hours. Similarly, thermal diffusivity increases with both aging time and temperature, peaking after aging at 200 °C for five hours. An SEM/EDS analysis shows the presence of finely dispersed precipitates that contain Mg, Si, and Fe. TEM investigation confirms the existence of nanometer-sized rod-shaped precipitates believed to be the strengthening β’’ phase.
