Description
Summary:The microstructure and properties of Al-Mg-Si alloy with different contents of B element were studied through microstructure, mechanical properties, and conductivity. The results showed that after adding the B element, the precipitates tended to precipitate along grain boundaries. As the amount of the B element increased, the grain coursing was severe, and the tensile strength was slightly improved. However, the impact on hardness was not significant, and the yield strength ratio showed a downward trend. When the addition amount of B element was 0.02wt.%, the Al-Mg-Si alloy had the best conductivity. Therefore, by comprehensive consideration of the conductivity and mechanical properties, the optimal addition amount of B was 0.02 wt.%.
