Abstract In order to improve the performance of 6016 aluminum alloy, the effects of the rare earth Y and the heat treatment process on the microstructure and tensile properties of 6016 aluminum alloy were studied by means of OM, SEM, XRD, TEM and EBSD. The results show that with the addition of Y, the grain of 6016 aluminum alloy is obviously refined, and the grain distribution tends to be uniform. When the addition of Y is 0.35wt%, the grain refinement effect, strength and elongation of the alloy reach the best value. However, when the element Y is added too much, the mechanical properties are reduced under the same heat treatments condition. Element Y mainly exists in the form of Al₃Y and AlFeSiY compounds at the grain boundary, helping the nucleation rate of recrystallization increase, which is conducive to the development of small-angle boundary towards big-angle interface, and has a positive effect on the recrystallization process of alloy. 6016 aluminum alloy has good paint hardening. The tensile strength and yield strength of the alloy with 0.35wt%Y element are up to 320 MPa and 270 MPa after simulated paint baking for 6 h. Compared with its T4p state, the tensile strength is improved by 68 MPa and the yield strength is improved by 116 MPa.
