Resumo
TiFe compound was produced by high-energy ball milling of TiH2 and Fe powders,
followed by heating under vacuum. TiH2 was used instead of Ti in order to avoid the strong
particles adhesion to grinding balls and vial walls. Mixtures of TiH2 and Fe powders were drymilled in a planetary mill for times ranging from 5 to 40 hours. The amount of sample, number and
diameter of the balls were kept constant in all experiments. After milling, samples were heated
under dynamic high-vacuum for the synthesis reaction. As-milled and heat-treated materials were
characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and differential
thermal analysis (DTA). The mean crystallite sizes and microstrains were determined by XRD line
profile analysis using the Warren-Averbach method. As-milled materials presented only Fe and
TiH2 phases. Nanostructured TiFe compound was formed after heat treatment. TiH2 was effective
for providing low adherence of the powders during milling.
