| Abstract: | Addressed is the effect of ball milling on aluminothermic reduction of TiO2. In 0.5-h milled 3TiO2 + Al mixtures, a two-step reaction was found to yield TiAl and Ti3Al. Upon an increase in the milling time (to 20 h), a one-step reaction yielded TiAl. The activation energy for TiAl formation was 75 kJ mol−1 for 0.5-h milled samples and 33 kJ mol−1 for 20-h milled samples. The article is published in the original. |
