Механохимический синтез интерметаллического соединения TiFe из элементарных порошков железа и титана

Abstract

It has been studied the structure and phase composition of the intermetallic compound TiFe, obtained by mechanochemical synthesis from elemental iron and titanium powders. After mechanical treatment, the Ti-Fe powder mixture (50 wt. %) contained α-Ti and α-Fe. The cell size of the α-Ti phase after mechanical treatment remained unchanged and was equal to 0.2867±5·10-4 nm. The cell size of the α-Fe phase decreased as the treatment duration increased. The TiFe intermetallic compound is formed at 300 seconds of mechanical treatment
