Abstract

Basic principles and recent developments of the Whole Powder Pattern Modelling (WPPM) approach are briefly reviewed and illustrated by a typical case study: a highly deformed metal powder (AISI 434) produced by high energy ball milling. Microstructural parameters, like crystalline domain size distribution, dislocation density, and arrangement parameters, are directly obtained by modelling the experimental pattern, without using arbitrary analytical profile functions.

Keywords: Whole powder pattern modelling; Line profile analysis; Nanocrystalline materials; Dislocation density; Powder diffraction

  1. 1

    The IP for a well collimated diffractometer, with suitably narrow slits and a diffracted beam monochromator, is symmetrical, so the corresponding FT is a real function. As an alternative, a Fundamental Parameter Approach (FPA) can be adopted to synthesize the IP (e.g., see [7]).
