Migration of vacancies to stress centers


Vermilya, Jay J. (1956) Migration of vacancies to stress centers. Engineer's thesis, California Institute of Technology.


The activation energy for motion of a vacancy in an edge dislocation width is considered by a modification of the method of Bartlett and Dienes. The results indicate an expected trend of motion toward the center of the width in the compressed half with a decreasing activation energy from edge to center. On the basis of the model used there is little tendency to form nonequilibrium vacancy doublets by this mechanism.
