Abstract

Heat treatment is an effective method to improve the mechanical properties of 6xxx-series aluminum alloys through the precipitation hardening mechanism. This study aims to analyze the effect of variations in artificial-aging temperature and holding time on the microstructure and hardness of aluminium alloy 6063 and to identify the correlation between them. The research method employed was experimental, consisting of solution treatment at 530 °C for 120 minutes, followed by water quenching and artificial aging at temperatures of 195 °C and 210 °C for durations of 160 and 190 minutes. The testing methods included microstructural observation and precipitate analysis using SEM-EDS, hardness testing using the Vickers method, and quantitative precipitate analysis. The results indicate that variations in artificial-aging parameters significantly affect the number, size, and distribution of Mg₂Si precipitates. Artificial aging at 210 °C for 160 minutes produced fine and homogeneously distributed precipitates, resulting in the highest hardness value of 73.14 HV, whereas aging at 210 °C for 190 minutes led to over-aging, reducing the hardness to 66.50 HV.
