摘要：

The effects of different solution methods on microstructure, mechanical properties and precipitation behavior of Al-Mg-Si alloy were investigated by scanning electron microscope, transmission electron microscope, tensile test, and differential scanning calorimetry The results revealed that the recrystallized grams of the alloy after the solution treatment with hot air became smaller and more uniform, compared with solution treatment with electrical resistance The texture of the alloy after two solution treatment methods was different More rotated cube components were formed through solution treatment with electrical resistance, which was better for improving the drawability of the alloy The strength of the alloy under the solution treatment with hot air was higher before stamping, because of the small uniform grams and many clusters in the matrix The alloy solution treated with hot air also possessed good bake hardenability, because the transformation occurred on more clusters in the matrix.
