Abstract

From measurements of X-ray and neutron scattering of electrostatically levitated Zr₇₇Rh₂₃ liquids, a variety of metastable crystallization behavior was observed. The metastable phase selection in deeply undercooled liquid droplets is characterized and their crystallization pathways discussed. A metastable phase previously identified as a primary devitrification product from the metallic glass formed when undercooling was maximized to near the hypercooling limit. The direct formation of α–Zr and the equilibrium C16 phase as well as a newly discovered Zr₅Rh₃ (Mg₅Si₃-type) phase are also reported.
