Abstract
Dislocation images giving double contrast in the electron microscope for g·b=2 have been reexamined as a possible means for Burgers vector determinations. In fcc foils which have been cut parallel to an active slip plane, the g·b=2 critierion provides a quick positive Burgers vectoranalysis which can be carried out during observation. The method is also applicable to basal dislocations in hcp. A comparison between calculated two‐beam profiles and experimental images in aluminum is discussed and several commonly observed characteristics of g·b=2 contrast are described.This publication has 7 references indexed in Scilit:
