Abstract. It has been shown that nanometersize grains can be induced in even brittl e intermetallic compounds by high energy ball milling. The large grain boundary area provided by these nanocrystallites can help provide, along with the disordering energy, the driving free energy for the crystallinetoamorphous transformation.

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.
