Isothermal Nanocrystallization Behavior of Zr_(41.25)Ti_(13.75)Ni_(10)Cu_(12.5)Be_(22.5) Bulk Metallic Glass in the Supercooled Liquid Region

摘要

The isothermal crystallization of Zr_(41.25)Ti_(13.75)Ni_(10)Cu_(12.5)Be_(22.5) (at. percent) bulk metallic glass in the supercooled liquid region is studied by X-ray diffraction, differential scanning calorimetry and transmission electron microscopy. The kinetics and the underlying mechanisms for the nucleation and growth of the crystalline phases precipitated in the two-stage crystallization process are discussed.
