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 ...

The ball dimensions were 305 mm × 305 mm, and number of revolutions was 70 revolutions/min. A mill charge for a single grinding operation was equal to 1100 g. The total grinding time was 10 min, but at every 2 min, the process was stopped and the particle size distribution (PSD) analysis was carried out. Five PSD analyses in total were ...

General considerations. Energy is usually and most simply defined as the equivalent of or capacity for doing word itself is derived from the Greek energeia: en, "in"; ergon, "work."Energy can either be associated with a material body, as in a coiled spring or a moving object, or it can be independent of matter, as light and other electromagnetic radiation traversing a vacuum.

Milling was then performed in 80% ethanol for 30120 minutes using a highenergy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intrafibre swelling.
