Monte Carlo simulations of XRF intensities in non-homogeneous matrices

In this paper a quantitative explanation is formulated for many discrepancies in the analysis of non-homogeneous materials. Metal alloys are the examples by excellence of such materials. Fe-Cr and Zn-Al alloys with a dispersed phase containing one of the elements only or both elements in a concentration different from the bulk, are simulated. Monte Carlo methods are used for generating the dispersions as well as for simulating the XRF processes.
