Stacking Faults in Zinc

Abstract
Configurations of individual dislocations in zinc have been studied by electron transmission microscopy and by x‐ray diffraction microscopy. Loops of sessile dislocation have been observed surrounding stacking faults lying on (0001) planes. These loops were evidently formed by condensation of point defects. Changes in loop size with climb of the surrounding dislocation have been observed occurring in the electron microscope. Separation of glissile dislocations into partial dislocations separated by stacking faults on (0001) planes have also been observed. Various interactions among the several types of dislocations occur.
