A method for measurement of dislocation link length distribution (i.e. distribution of spacings between connected nodes) from transmission electron micrographs is given. The method is based on measurements of projected lengths of all links fully situated in the foil. By statistical corrections this two-dimensional distribution is converted to a three-dimensional distribution.
The method has been applied to specimens of creep-deformed, polycrystalline MgO and an empirical equation for the distribution has been found. Also the influence of non-uniformity of the Frank network on the magnitude of β in the equation Lav = β√ρ is considered.
