Electron-microscope examination of a pure iron and two commercial low-carbon steels has enabled the driving force for recrystallization to be evaluated as a function of orientation. The two classical approaches to annealing-texture development, the oriented-growth and the oriented-nucleation theories, have been compared on the basis of the results obtained and it is concluded that in the early stages of recrystallization oriented nucleation predominates in the selection of orientations.
