Abstract
Precipitation and dissolution reactions in Al-2.33wt%Li-0.32wtZr alloy were examines by employing adiabatic scanning calorimeter. The results obtained were as follows. The δprecursor phase was appeared immediately during quenching and was precipitated at the higher temperature(433k) than the miscibilty gap of Al-2.33wt%Li binary a1loy. It dissolved in the 360-463K temperature range with an enthalpy typical of GP zones as like other Al base alloys, and the kinetics of its dissolution were also similar to those of other GP zones. Two endothermic reactions appeared in the lower temperature than the reversion temperature of δphase were corresponding with those of dissolution of GP zones in Al-Li binary alloys.
