Atomic-Scale Investigation on the Evolution of Tio-Anatase Prepared by a Sonochemical Route and Treated with NaOH.

To date, the formation mechanisms of TiO, as well as its heterostructures, have not been clarified. Moreover, detailed research on the transition from a tetragonal anatase phase to the monoclinic phase of the TiO(B) phase and their interface structure has been quite limited until now. In the present study, we report on the sonochemical synthesis of TiO-anatase with a crystallite size of 5.

Intercalated Intermetallic Compounds AlTi and FeTi in Microrods and Microtubes Obtained by Invariant Reaction of Mechanically Milled System AlTiFe.

This paper reports the production of intermetallic microrods and microtubes from the decomposition of an intermetallic compound in an AlTiFe system. The intermetallic compound was obtained by mechanosynthesis of elemental powders of Al, Ti and Fe over 300 h at 400 rpm, sintering from compacted powder particles at 300 MPa per minute and at 900 °C for 3600 s in an argon atmosphere. The milled and sintered samples were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM).
