图9. 不同降温时间点试样的DSC曲线(Tp=225 ℃)
Fig.9. DSC curves of the samples under different cooling temperature (Tp=225 ℃. 164 and 25 are the different temperatures during the cooling process. C represents the cooling ageing. The arrow indicates the movement of dissolution temperature to lower level because the secondary precipitation occurred during cooling)
