Abstract

This research aimed to improve the mechanical properties of Al6061 alloy through artificial aging heat treatment. The method used in this research was a laboratory-based experimental method. The Al6061 alloy was heated in a muffle furnace at a temperature of 480°C and held for 30 minutes. Next, rapid cooling (quenching) was carried out using cooling media of dromus oil. Then, specimens were reheated at 190°C for 2 hours, 4 hours and 6 hours for artificial aging process. The heat-treated specimens were tested for microstructure and hardness numbers. The data obtained were compared and analysed using image-J software. The research results showed that the smallest grain diameter was obtained in specimens treated with artificial aging for 4 hours, which was 47.633 µm. In this specimen, the β-Mg2Si phase was found to be 19.752 %. The highest hardness number was obtained in specimens with the same variation, which was 110.8 HRE.
