This research aimed to explore the effect of artificial aging temperature variations on toughness, hardness, microstructure, and fault morphology in AlMgSi. 120°C, 150°C, and 180°C with 6 hours of holding time were used as the variations. Impact tests used the ASTM E23 standard, and showed an increase in specimen toughness given artificial aging that peaked at 180°C with 0.0649 kg/mm2. Microstructure exhibited a sparse precipitate in the specimen with artificial aging. The fault morphology showed that specimens with artificial aging had brittle and ductile fractures.
