Abstract

Cobalt and boron powder mixtures with differing Co/B ratios were ball milled under high energetic conditions at room temperature. X-ray diffraction and transmission electron microscopy measurements were carried out on the powders. The study has shown that energetic conditions of milling affect the process by which the amorphous state is produced. The amorphous state was completely reached in all the systems with an evolution rate which depended on boron content; in particular it increased in the order Co50B50>Co60B40>C67B33. The alloys at the maximum amorphous stage have a structure similar to amorphous TM-B alloys obtained by rapid quenching techniques.
