Study of X-ray diffraction profiles of a Ti-13Ta-3Sn alloy obtained by mechanical alloying

ABSTRACT The Ti-β alloys have become highly demanded in industry, due to their good physical and chemical characteristics. In the present work, a Ti-13Ta-3Sn (%at) alloy was synthesized using mechanical alloying (MA) between the times of 2 and 100h. The alloys were characterized by X-ray diffraction (XRD) and analyzed by the Rietveld method with the MAUD software. The microstructural changes and the evolution of the Ti-α and Ti-β phases were characterized. Identifying the presence of a new metastable fcc phase and the synthesis of an alloy with 79.80%wt of Ti-β phase, both alloys with nanometric crystallite size.
