| Abstract |
The effect of In and Be addition on the aging behaviors in Al-Cu-Li alloy has been studied with the differential scanning calorimetery(DSC) and the transmission electron microscopy(TEM). The addition of In in Al-Cu-Li alloy retards the formation of GP zone and δ′ phase, whereas it promotes the formation of T₁ and θ′ phases. However the formation of T₁ and θ′ phases as well as the formation of GP zone and δ′ phase are promoted by the addition of In and Be in Al-Cu-Li alloy. |
