Figure 5
Quantitative analysis confirms that the N2V method preferentially recovers the size of smaller grains. The histogram plots the change in grain size for the N2V reconstruction relative to the traditional method (reference). The data clearly show that for grains smaller than 20 µm, a larger number of grains are reconstructed as larger (red bars) than smaller (blue bars). The green line (right axis), representing the mean size change, confirms this trend. This indicates a correction of the systematic undersizing of small grains that occurs in traditional processing, and a slight erosion of large grain boundaries.
