Study on Amorphization of Mechanical Alloyed Cu₅₀Zr₄₀Ag₁₀ Alloy

Abstract:

The amorphization and crystallization of mechanical alloyed Cu₅₀Zr₄₀Ag10 alloy have been investigated using X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The results demonstrate that a full amorphous phase of Cu₅₀Zr₄₀Ag₁₀ can be obtained through mechanical alloying. The amorphous phase begins to show the initial mechanical crystallization when the milling time is 108 h and subsequently the main milling product is still amorphous structure with increasing milling time up to 208 h. Therefore, the amorphous alloy exhibits the excellent mechanical stability during mechanical alloying. The nearest-neighbor distance of atoms firstly increases then reduces with the increasing milling time, indicating that there is a closely correlation between the initial crystallization behavior and short range ordering.
