An amorphous Cu0.6Ti0.2Zr0.2 alloy was synthesized by mechanical alloying of pure elemental powders of Cu, Ti, and Zr in air using a planetary high-energy ball-milling machine. The structure and thermal behavior of the powders milled for different times were analyzed by x-ray diffraction and differential scanning calorimetry. Results indicate that adding Zr into the Cu-Ti binary system can speed the amorphization. Furthermore, the alloy composition during the milling process may influence the ratio of Zr crystallization products relative to those of Ti.
