Abstract

In this study, the impact of multistage solid solution treatment on the microstructure and properties of the Al-6.5Si-5.5Cu-0.2Zr-0.01Sr-0.06Ti-0.2Y alloy was examined using various experimental techniques such as optical microscopy, scanning electron microscopy, x-ray diffraction, transmission electron microscopy, and tensile testing. The findings demonstrated that with an increase in the multistage solid solution temperature and duration, the θ phase (stable Al2Cu) and intermetallic compounds gradually dissolved into the α-Al matrix, leading to a reduction in the residual phase content. The Si phase’s equivalent diameter decreased as the solid solution temperature increased, resulting in the spheroidization of eutectic Si, thereby contributing to dispersion strengthening. Consequently, the gradual rise in dislocation density and sample strength led to an enhancement in tensile strength. The G3 solid solution treatment (470 °C × 2 h + 480 °C × 2 h + 490 °C × 2 h + 500 °C × 2 h + 510 °C × 2 h + 520 °C × 14 h) demonstrated optimal mechanical properties with the ultimate tensile strength reaching 353.58 MPa and a fracture elongation rate of 9.25%. Moreover, this treatment exhibited superior corrosion resistance, as evident from the intergranular corrosion with a maximum depth of 69.36 μm, an electrochemical corrosion potential of − 1.1895 V, and a corrosion current density of 1.9965 × 10−7 A/cm2.
