Abstract
The statistical methods for detection and characterization of solute clustering and ordering have been examined both in actual atom probe experiments and with the use of Monte-Carlo computer simulations. The results have indicated that whereas the Hetherington and Miller mean separation method is more appropriate to detect clustering, the Johnson and Klotz order parameter method is required to detect short range order in concentrated solid solutions.
