Amorphization Induced By Ball Milling In Some Pure

Abstract. We report on the crystal to amorphous phase transition induced by ball milling in pure Si and pure Ge powders. Based on X-ray diffraction patterns, scanning and transmission electron micrographs, EDX microanalyses, differential thermal analyses and differential scanning calorimetry, it seems that amorphization occurs during the continuous decrease of the particle grain size and ...

Amorphization mechanisms of NiZr2 by ballmilling

Amorphization Mechanisms Of Nizr2 By Ballmilling

The microstructure of NiZr 2 in the course of amorphization by ball-milling is studied by transmission electron microscopy TEM and x-ray diffraction XRD. The evolution from the initial fully crystalline alloy to a fully amorphized material is described. It is shown that prior to amorphization, the powder aggregates achieve a 100 nanocrystalline structure the amorphous phase then appears ...
