Abstract
A statistical analysis was made to understand how strongly the population of the boundary in vapor-grown iron bicrystals is influenced by the energy cusp.
Electron channeling pattern with an error limit better than 0.1° was applied to resolve the problem. It was concluded that they are only distributed about the coincidence orientations.
The observed distribution was very heterogeneous; The major component of the misorientation from the perfect coincidence was of the tilt type. The result is explained if the population of the grain boundary is controlled by the energy and the boundary within the energy cusp is composed of a grain boundary dislocation network superimposed upon the coincidence related boundary.
