Characteristics of BMG specimens during flash-annealing. (a) Heating curves of Cu₄₆Zr₄₆Al₈, Cu₄₄Zr₄₄Al₈Hf₂Co₂ and Zr_52.5Cu_17.9Ni_14.6Al₁₀Ti₅ BMG specimens flash-annealed at indicated heating rates and temperatures (below and above T _x). (b) XRD patterns of the flash-annealed and as-cast glasses. The patterns of the specimens flash-annealed above T _x display sharp reflections originating from crystals. The heating rates, annealing temperatures and crystalline phases are indicated.
