图8. 不同升温时间点试样的DSC曲线(升温速率为3 ℃/min)

Fig.8. DSC curves of the samples at the different heating temperatures (heating rate is 3 ℃/min. 3 represents the heating rate of 3 ℃/min. 130, 176, 207 and 225 are the different heating temperatures during the heating process. S represents water cooling treatment. The arrow indicates the movement of dissolution temperature to higher level because the precipitates became more and more thermal stable during the heating process)
