Abstract

Cr₉₀Co₁₀ and Cr₁₀Co₉₀ mixtures were mechanically alloyed in order to obtain nanocrystalline alloys. The obtained powders were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The structural parameters such as the lattice parameters, the crystallite size, the microstrains and the defect density of the different phases were deduced from the Rietveld refinement of the XRD patterns using the MAUD program. For the Co-rich mixture the evolution with milling time of the SEM micrographs shows a tendency of particle agglomeration. However, in the case of the Cr-rich mixture, the particles tend to the fragmentation. The Rietveld refinement of XRD patterns of the Cr₁₀Co₉₀ mixture reveals the formation of disordered hcp and fcc Co(Cr) solid solutions. In the case of the Cr₉₀Co₁₀ mixture, only a disordered bcc Cr(Co) solid solution is obtained. The changes in the morphology and the structure of the two mixtures are explained on the basis of the mechanical and structural properties.

 and Cr<sub>10</sub>
Co<sub>90</sub>
 mixtures were mechanically alloyed in order to obtain nanocrystalline alloys. The obtained powders were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The structural parameters such as the lattice parameters, the crystallite size, the microstrains and the defect density of the different phases were deduced from the Rietveld refinement of the XRD patterns using the MAUD program. For the Co-rich mixture the evolution with milling time of the SEM micrographs shows a tendency of particle agglomeration. However, in the case of the Cr-rich mixture, the particles tend to the fragmentation. The Rietveld refinement of XRD patterns of the Cr<sub>10</sub>
Co<sub>90</sub>
 mixture reveals the formation of disordered hcp and fcc Co(Cr) solid solutions. In the case of the Cr<sub>90</sub>
Co<sub>10</sub>
 mixture, only a disordered bcc Cr(Co) solid solution is obtained. The changes in the morphology and the structure of the two mixtures are explained on the basis of the mechanical and structural properties.</s0>
