Abstract
Three amorphous alloy powders in the Ti-Fe system with the ratios of Ti:Fe at 1:2, 1:1, and 2:1 were prepared by mechanical alloying of the elemental powders in a high-energy ball mill. The amorphous powders were characterized by x-ray diffraction and high-resolution transmission electron microscopy. A complete amorphization of Ti 1 Fe 1 was achieved, whereas a remaining crystalline portion besides the amorphous phase was present in Ti 2 Fe 1 and Ti 1 Fe 2 . The crystallization temperatures for these alloys detected by differential scanning calorimetry varied from 714 to 791 K, which were corresponding to half of their melting points.
