Electric-field-enhanced crystallization of Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass

Isothermal crystallization studies are performed on Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass (BMG) with and without applied electric field. The crystallization process of the BMG is markedly affected by the applied electric field. The crystalline phase volume fraction and the growth rate of nucleus are enhanced when annealed in the electric field in the supercooled liquid region. We phenomenologically explain the observations.
