Microstructural characterization of nanocrystalline chromium carbides synthesized by high energy ball milling

Nanostructure chromium carbides were fabricated by mechanical alloying in a Fritsch planetary ball mill. The morphological changes and the effect of milling time and elementary powder compositions on final products were investigated by employing scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that although at early stages of milling the solid solutions were formed, but the final products for prolonged milling...
