Pressure-temperature-time-transition diagram in a strong metallic supercooled liquid

Wang, W. H.*; Utsumi, Wataru; Wang, X. L.*

The crystallization kinetics and nucleation mechanism of a bulk metallic glassforming alloy Zr $_{46.75}$ Ti $_{8.25}$ Cu $_{7.5}$ Ni $_{10}$ Be $_{27.5}$ (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 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.
