Evaluation of Differences in the Estimated Recrystallized Volume Using Different Methods Based on EBSD Data
There are several methods that have been developed in the last decade which use the data extracted from EBDS measurement for the purpose of determining the recrystallized volume of deformed and annealed metals. Two general ideas could be identified: calculations based on the quality of indexing of the scanned points and calculations relying on the differences in crystallographic orientations. First, a simple method is presented utilizing the Image Quality (IQ) indexing of the EBSD data. Estimations were also made analyzing the orientation maps resulted from the same measurements. In the final section the applicability of the IQ based method is discussed in comparison to the misorientation (MO) technique. Based on the accuracy of the measured and calculated results the proposed method seems useful although both procedure offer unreliable estimations at low recrystallization rates.
