文摘

The Ag-containing alloy had relatively lower T4 hardness compared to the Cu-containing alloy. Ag addition improves the precipitation kinetics during AA for the strong interaction between Ag, Mg and vacancy. The negative effect of NA is decreased by the addition of Ag or Cu, especially combination.
