Measurement of the fine structure factors and extinction distance by convergent-beam electron diffraction in Co3Ti with and without B doping

Using convergent-beam electron diffraction (CBED), the fine structure facto rs of Co3Ti alloys have been measured and the effects of boron microalloyin g on the fine structure factors have been studied. The extinction distances of Co3Ti have been obtained by both Kelly's method (making use of the posi tions of the maximum and minimum intensities in the CBED pattern) and the C BED simulation method.
