Preparation and hydrogen absorption property of amorphous Ti50Fe50

Substitutional effects in TiFe for hydrogen storage: a comprehensive review

“…To simplify the activation, Chu et al [85] synthesized TiFe by means of mechanical alloying, starting from elemental powders of Ti and Fe. The authors prepared an equiatomic TiFe mixture, ball-milled for different duration times.…”

Synthesis of Ti–Fe alloys by mechanical alloying

“…A large number of works on hydrogen absorption and activation properties for TiFe alloys produced by MA or MG has been reported [28][29][30][31][32]. However, most studies were focused on the improvement of activity of the alloy to hydrogen gas.…”

Synthesis of TiFe Compound from Ball Milled TiH₂ and Fe Powders Mixtures

“…4 can be related mainly to the TiFe compound formation. It should be said that in the temperature range of this first peak other authors verified a recrystallization of the amorphous TiFe [1,9]. A second and last exothermic event, weaker than the first one, is seen on each curve ranging from 730°C to 740°C.…”

“…TiFe intermetallic compound has been normally produced by mechanical alloying through highenergy ball milling of titanium (Ti) and iron (Fe) powder mixtures in order to improve their properties concerning hydrogen storage (absorption and desorption) [1][2][3][4][5][6][7][8][9]. Several authors associated this improvement with formation of nanostructures during the milling process (nanocrystalline TiFe) [5][6][7][8][9].…”
