摘要：

The effects of high pressure on nucleation of Cu60Zr20Hf10Ti10 bulk metallic glass (BMG) are studied by means of differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The activation energies of crystallization for the BMG at different pressures are determined by the Kissinger method. The experimental results demonstrate that applied pressure promotes nucleation. The effects of high pressure on nucleation are discussed in terms of the nucleation kinetics and thermodynamics. (C) 2004 Elsevier B.V. All rights reserved.
