Warren plot comparing results of Fig. 11, obtained from the Warren–Averbach analysis of profile data from the DSE pattern (filled symbols), with the standard deviation of the strain distribution directly calculated from the D-PDFs. Results refer to the microstructure of Fig. 1 after MD equilibration (a) and after removal of one atomic layer from the surface of all grains in the cluster (b). The full line in (a) indicates the equivalent thermal strain at melting temperature.
