Abstract
We have studied the effect of the milling energy and atmosphere on the crystalline-amorphous phase transition induced by ball milling of Si and Ge powders. It was found that the amorphization process is caused by grain refinement. A strict correlation between the milling energy a nd amount of amorphous phase obtained was determined. The effect of ox ygen on the amorphization process was investigated. No correlation was found between the level of oxygen contamination and the formation of the amorphous phase. The effect of oxygen on the thermal properties of the amorphous phases was studied.
