View submission: Guinier-Preston zones
These zones don't have a constant concentration of solute throughout their volume, right? It's a gradient?

More like they deplete the surrounding areas until they hit equilibrium for whatever temp they are precipitating at.

Don't really know, what I know (I've re-read my lecture notes) is that GP zones are like small disks constituted with solute atoms, they are coherent with the matrix even if there is a small distortion.
What's more interesting is that along the precipitation sequence of AlCu alloys, you form others precipitates which are larger : θ'' and θ'
