Fabrication of Fe-Ti Alloys by Pulsed Current-Assisted Reaction from Iron, Manganese and Titanium Oxide or Titanium Hydride

다국어 초록 (Multilingual Abstract)

Fe-Ti alloys were prepared by applying a pulsed electric current through compacted mixtures of iron,manganese and titanium oxide (with carbon) or titanium hydride (without carbon). After ball milling the mixture into a fine powder, the mixture was heated up to 1373-1573 K in a carbon mold by applying a pulsed electric current, and the temperature was maintained for 3-10 min. When TiO2 was used as a starting material, TiC was formed. Fe was alloyed into FeTi and Fe2Ti, with Ti also observed. When the C content was lowered to 8.136 wt%, the remaining C content after pulsed current application decreased to 4.64 wt%. When using TiH2 as a starting material, Fe was alloyed into FeTi and Fe2Ti, and Ti, Mn, Fe,and FeMn2 were also observed. For a Fe-Ti alloy prepared using titanium hydride as a starting material,hydrogen content vs. absorption time curves were obtained at various numbers of cycles and temperatures.
