摘　　要：利用非等温差热扫描量热分析方法及Kissinger方程,研究了H原子对Zr-Ti-Cu-Ni-Be块状非晶合金玻璃转变 和晶化的激活能影响.结果表明, H能够提高玻璃转变温度和晶化温度,增加玻璃转变和晶化激活能;引起晶化不同阶段热焓减 少;并且充入H能降低玻璃转变温度和晶化温度对加热速度的依赖程度.The effects of hydrogen on the activation energy and the kinetics of glass transition and crystallization of Zr-Ti-Cu-Ni-Be bulk amorphous alloy were studied by differential scanning calorimetry (DSC) and the Kissinger equation. It is shown that hydrogen increases the glass transition temperature and the crystallization temperature and makes the enthalpy decrease in the different stages of crystallization. In addition, hydrogen increases the activation energies of the glass transition and the crystallization, and changes the kinetics effect. The dependant extent between the glass transition and the crystallization and heating rate is decreased after hydrogen charging.
