Abstract

Methods available for determining the crystallography of grain boundaries are surveyed. It is suggested that the reason why relatively few studies of the crystallography of large numbers of boundaries have been made is the intensity of labour involved in the data analysis. A scheme is described which allows a large sample population of grain boundaries to be handled with maximum efficiency, whilst maintaining high precision in the parameters which describe the boundary. It also permits a comparison of these parameters with those which describe special cases (e.g. high-density coincidence site lattice, etc). The method involves a combination of stereographic manipulation and matrix algebra.
