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.

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.File in questo prodotto:
