  • Synthesis of TiFe Compound from Ball Milled TiH2 and Fe

    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 dry-milled in a planetary mill for times ranging from 5 to 40 hours. The amount of sample, number and diameter of the balls were kept
