Resumen
Descripción
The effect of speed and milling time on the morphology, crystallite size, and phase composition of Ti Cp powders processed in n-hexane by high-energy ball milling (HEBM) using a E-max Retsch equipment was studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Lattice parameters, mean crystallite size, lattice strain, and dislocation density were obtained from Rietveld analysis. The XRD and TEM results show that the HEBM process of the Ti Cp promotes the transition from HCP to FCC after 6 h of milling at 1400 rpm. The transformation process could be attributed to the energy generated in the milling process which induces high deformation and presence of high-density dislocations in the powder.
