金属玻璃中的不同缺陷其激活能ε_0不同,每种缺陷的频率因子B也可能有数量级上的差别。基于这种思想,提出了确定金属玻璃结构弛豫谱的方法。通过测量等速升温下的电阻变化,确定了五种Cu-Zr合金玻璃的结构弛豫谱。所得谱包含三个分立的激活能峰,它们各具不同的频率因子,频率因子的值影响激活能峰的形状、范围、位置和连续性。Zr含量显著影响Cu-Zr玻璃的结构弛豫谱,讨论了其变化的规律性。 Different defects in metallic glass have different activation energies ε_0. The frequency factor B of each defect may also vary by an order of magnitude. Based on this idea, a method of determining the relaxation spectrum of metallic glass structure is proposed. The structure relaxation spectra of five Cu-Zr alloy glasses were determined by measuring the change of resistance at constant temperature. The resulting spectrum contains three discrete activation energy peaks, each with a different frequency factor whose value affects the shape, range, position, and continuity of the activation energy peak. Zr content significantly affects the structure relaxation spectrum of Cu-Zr glass, and discusses the regularity of its change.
