| 中文摘要 | An approach is developed using differential scanning calorimetry with the characteristics of relaxation to exhibit a glass transition under high pressure in metallic glass, specifically, the glass transition in Zr46.75Ti8.25Cu7.5Ni10Be27.5 bulk glass-forming alloy with a very stable supercooled liquid state. Through the approach, we obtain an averaged increase of the glass transition temperature with a pressure of 5.6 K/GPa. Based on free volume theory, the formation volume (DeltaV(f)) of 6.5+/-0.5 Angstrom(3) and migration volume (DeltaV(m)) of 6.5+/-0.5 Angstrom(3) for defect diffusion, which is related to pressure-dependent free volume change, are derived. The results contribute to the understanding of the nature of the calorimetric glass transition and diffusion in metallic glasses. |
