dc.description.abstractThis paper investigates the influence of ageing parameters (temperature and time) on the microhardness, electrical conductivity and structural properties of two Al-Mg-Si aluminium alloys. After the applied heat treatment, both microhardness and electrical conductivity were measured. Optical microscopy was used to investigate the microstructures after ageing. The heat treatment began by solutionizing the samples at 550°C for 1 hour, followed by quenching in ice water. Samples were then aged at two separate temperatures, 180°C and 200°C, for 1–8 hours. The results indicate that with the increase in ageing time, the microhardness gradually increases up to a maximum and then decreases, while the electrical conductivity continuously increases. Analysis on the optical microscope shows that with longer ageing, there is precipitation of a larger amount of the strengthening phases due to more intense diffusion of alloying elements from the solid solution.
