The coupling of all the employed experimental techniques in this work is crucial for detectingxperimental techniques in this work is crucial for detecting the precipitation of the Guinier-Preston zones. This is duehe precipitation of the Guinier-Preston zones. This is due to the strong changes in the microstructure produced by the main precipitation process, which starts at about 440 K and ends at about 640 K. We found that the temperature at which Guinier-Preston zones start to grow is about 473 K and that the dissolution temperature is 537 K. and that the dissolution temperature is 537 K. which Guinier-Preston zones start to grow is about 473 K and that the dissolution temperature is 537 K. and that the dissolution temperature is 537 K. and ends at about 640 K.
