Abstract

Two approaches are available for the analysis of the size and size distribution of the domains in a crystalline powder: pattern decomposition (or fitting) and pattern modelling. In the first case, the information is obtained from some fitting parameter and no direct connection exists between the model and the data; in the second case, a microstructure model is employed to simulate the peak profile and the model parameters are directly refined against the experimental data. The most common methods for the analysis are discussed and the formulae for the simulation of the size-broadened profile are provided.
