Boundary migration during the primary recrystallization of cold-worked material was studied by means of in situ heating in a scanning electron microscope. The rate of grain-boundary migration during recrystallization was plotted as a function of the driving force for recrystallization, as deduced from calorimetric measurements. It was shown that the change in boundary velocity agreed with the Cahn-Lücke-Stüwe theory of impurity drag.
