The coherent electron microdiffraction of a single translation domain boundary in β-Ni₃Nb phase

The microdiffraction from a single translation domain boundary (TDB) in β-Ni₃Nb has been recorded by using a Hitachi HF-2000 field emission gun transmission electron microscope, while high-resolution transmission electron microscopy images were used to assist the analysis. The diffraction splitting effect of a TDB is well explained by the kinematics and dynamic calculations, and complex diffraction characteristics have been studied by using dynamics simulation.
