中文摘要	The crystallization kinetics and nucleation mechanism of a bulk metallic glass-forming alloy Zr46.75Ti8.25Cu7.5Ni10Be27.5 (vit4) in the entire supercooled liquid region (SLR) is investigated using in situ high-pressure and high-temperature X-ray diffraction with synchrotron radiation, which allows us for the first time to simultaneously determine the crystallization kinetics and phase evolution of a metallic liquid as a function of time under high pressure. The results are summarized in a pressure-time -temperature-transformation ( PTTT) diagram with two time scales. The results suggest that the dominant crystallization mechanism of the BMG is growth-controlled.
