Estimation of recrystallized volume fraction from EBSD data

The recrystallized volume fraction is an important parameter in the study of recrystallization processes. This paper proposes a new method to estimate this parameter, based on quantitative EBSD data analysis, The principle of the method is first presented. The method is then tested on experimental EBSD data obtained on copper and brass. Estimated recrystallized volume fractions for different annealing temperatures are compared with values estimated from micro-hardness measurements. The presented method appears to be precise and very easy to implement, provided that some conditions are met; these are discussed in the final section. (C) 2002 Acta Materialia Inc.
