摘要：
By combining differential scanning calorimetry analysis and high-resolution transmission electron microscopy observations, the precipitation map for Al-Cu-Mg alloy (AA2024-T3) is obtained for a wide temperature range from 85 to 250 degrees C and ageing durations from 1 to 10,000 h. For the first time, the appearance of equilibrium S-Al2CuMg phase is observed at 85 degrees C from 1000 h of ageing. Hardness values superposed with the precipitation map reveal that the maximum hardness for all studied temperatures is located at the frontier between S-phase + Guinier-Preston-Bagaryatski (GPB) zones and S-phase regions.
