Abstract

The crystallization mechanism and solid-state phase transformations in Cu46.5Zr48Al4Nb1.5 metallic glass upon isokinetic and isothermal annealing are studied by using conventional and fast-scanning differential calorimetry, electric current flash-annealing, electromagnetic levitation, and in-situ high-energy synchrotron X-ray diffraction. Continuous-heating-transformation and time-temperature-transformation diagrams mapping the formation and evolution of the Cu10Zr7, B2 CuZr, τ3 Zr51Cu28Al21 and τ4 Cu2ZrAl phases in dependence on heating rate and temperature are constructed. Cu46.5Zr48Al4Nb1.5 metallic glass shows an increased propensity for the Cu10Zr7 phase formation compared to the parent Cu47.5Zr47.5Al5 glass.
