Abstract

Natural aging for 11 days at room temperature was applied to 6063 industrial aluminium alloy after being solutionized and quenched in order to form clusters. The cluster formation led to increasing hardness and tensile strength. The samples were then subject to a high aging temperature at 250 °C for up to 5 min in the so-called reverse aging (RA) process. The effect of RA was measured using hardness and tensile measurements, differential scanning calorimetry (DSC) and a scanning electron microscope (SEM). The tensile fracture surface morphology was investigated using the SEM. The natural secondary aging following RA was investigated as well. An understanding of the microstructure behavior after RA is established. The results showed that even the state of maximum reversion still contains undissolved clusters that contribute to hardness, tensile strength and DSC. At longer RA times, clusters grow and form strengthening precipitates. A state of clusters dissolution and clusters formation and growth is expected as free atoms can surround the non-dissolved clusters.
