The eCMWP fitting for reflection (220) of the Cu–3 at.% Ag sample in cryorolled
state, and after annealing for 20 min at 623 K. The symbols and the solid lines
represent the measured data and the fitted curves, respectively. The diffraction
peak in the annealed condition is a sum of two reflections related to Regions 1 and 2
having different average lattice parameters (for details see the text). In this figure
the integrated intensity (the area under the peak after background subtraction) is
normalized to unity for both cryo-rolled and annealed states.
