Resumen
ABSTRACT: Commercial powders of pure magnesium were processed by high-energy ball milling. The
microstructural and morphological evolution of the powders was studied using scanning electron
microscopy (SEM), energy dispersive spectrometry (EDX) and X-ray diffraction (XRD). From the
results obtained, it was determined that the ball size is the most influential milling parameter. This
was because balls of 1 mm diameter were used after a previous stage of milling with larger balls
(i.e., 10 and 3 mm). The powder particles presented an unusual morphology with respect to those
observed in the Mg-milling literature and recrystallization phenomena. Moreover, the result strongly
varied depending on the ball-to-powder weight ratio (BPR) used during the milling process. COL0007927 1.329.112.206
