Whole Powder Pattern Modelling of cubic metal powders deformed by high energy milling

A Whole Powder Pattern Modelling of the diffraction pattern has been used to study the effect of grinding on some cubic metal powders: crystalline domain size distribution, unit cell parameter average dislocation density, effective outer cut-off radius, effective (screw-edge) dislocation character and faulting probabilities provide a detailed picture of the microstructure of heavily deformed metals.
Besides proving the effectiveness of the analytical approach, the present study also suggests some generalization in the behaviour of pure powders of cubic metals subjected to an extensive high-energy milling.
