摘要：
Three Cu-Zr-Ti plate-like amorphous alloy composite powders were prepared by ball milling the corresponding alloy powders. Their crystallization behaviors are systematically investigated by non-isothermal and isothermal modes. The phase transition during the ball milling would be Cu51Zr14 -> amorphous+Cu51Zr14 for Cu70Zr15Ti15, Cu51Zr14+Cu -> amorphous+Cu+Cu51Zr14 -> amorphous+Cu for Cu80Zr10Ti10, Cu+Cu3Ti -> amorphous+Cu for Cu90Zr5Ti5, respectively. The crystallization temperature increases according to the sequence of Cu70Zr15Ti15, Cu80Zr10Ti10 and Cu90Zr5Ti5. The crystallization phases are Cu3Ti and Cu for the isothermal crystallized Cu70Zr15Ti15, the nonisothermal and isothermal crystallized Cu80Zr10Ti10, and the nonisothermal crystallized Cu90Zr5Ti5. The crystallization phases are Cu51Zr14, Cu3Ti and Cu for the nonisothermal crystallized Cu70Zr15Ti15, while Cu for the isothermal crystallized Cu90Zr5Ti5. The detailed crystallization mechanism of nonisothermal and isothermal modes are discussed.
