Correlation between Ball Milling Parameters and Microstructure .

In spite of a lot of research effort, the mechanism of phase formation during ball mill- ing (MA) is not well understood. It is most of- ten proposed that the process of MA introduc- es a variety of defects (vacancies, dislocations, grain boundaries, stacking faults, etc.) which raise the free energy of the system making it possible to.
