Abstract
A method for determining the position of dislocation lines accurately from dislocation images is reported and applied to the case of measuring the separation of partial dislocations. A theoretical analysis of the method is given, and the predictions verified by many-beam computed image profiles. The separation of partial dislocations in Cu + 10at. % Al has been determined using the method. The separation was found to be 120±20 Å. Other applications of the method are suggested.Keywords
