However, the intercept count N-L is directly related to the mean value of grain boundary area per unit volume S-V and the profile count N-A is, under relatively general assumptions, directly related to the mean value of grain junctions per unit volume L-V. Their relation to N-V can be generally written as N-V = c'(N-A)(3/2) = c ''(N-L)(3), but the coefficients c' and c '' strongly depend on the structural characteristics like grain size dispersion, anisotropy etc. and their evaluation is far from being simple. Consequently, whereas the reliable estimates of S-V and L-V result from intercept and profile counts, the estimate of grain density based on them requires a careful consideration.
