Abstract
Observations in the photoemission electron microscope and the optical microscope have been made on cold-worked copper specimens to ascertain the effect of a free surface on some aspects of the annealing kinetics. It can be shown that the kinetics of recrystallization at the surface is little, if at all, different from that of the recrystallization taking place simultaneously in the specimen bulk. Grain coarsening, on the other hand, starts invariably at the free surface and proceeds inward, so that only the beginning of this annealing stage can be investigated by continuous surface observation.
