Commercial powders of pure magnesium were processed by highenergy ball milling. The microstructural and morphological evolution of the powders was studied using scanning electron microscopy (SEM), energy dispersive spectrometry (EDX) and Xray diffraction (XRD). From the results obtained, it was determined that the ball size is the most influential milling parameter. This was because balls of ...
