摘要：

The effects of quenching under high pressure on crystallization of Cu60Zr20Hf10Ti10 (at.%) bulk metallic glass are studied by means of differential scanning calorimetry and X-ray diffraction. The temperature-time-transition diagrams of the alloy quenched under high pressure and the cast state are determined and compared. The crystallization process under different conditions is simulated based on the Johnson-Mehl-Avrami equation. The experimental results demonstrate that the pressure promotes the nucleation. The effects of high pressure on crystallization are discussed in terms of crystallization kinetics and thermodynamics. (c) 2008 Elsevier B.V. All rights reserved.
