A Mossbauer effect and X-ray diffraction investigation of Ti-Sn intermetallic compounds: II. Nanostructured phases prepared by ball milling with Al2O3 and TiN

A thorough X-ray diffraction and 119Sn Mossbauer effect investigation of Ti3Sn, Ti2Sn, Ti5Sn3, Ti6Sn5, and Ti2Sn3 phases ball milled with Al2O3 and TiN has been made. The starting compounds were verified to have the same crystal structures as those reported in the literature. X-ray diffraction data showed a decrease in grain size of the Ti-Sn phase with increased milling time and no interactions between the Ti-Sn phase and the Al2O3 or TiN. The two samples with the highest Sn concentrations (Ti2Sn3 and Ti5Sn6) were observed to precipitate elemental Sn when ball milled. This Sn precipitation was observed qualitatively by X-ray diffraction patterns and quantitatively by site populations reported in the Mossbauer spectroscopy data.
