(A) Stabilization of the Y₆₃Zr₂Cu₂₀Al₁₅ MG against crystallization through sub-T_g annealing. (B) FSC curves exhibit the effect of annealing at various temperatures T_a for 30 min on the sub-T_g relaxation behavior. The heating rate of those curves is 400 K/s. (C) Plotting the peak temperature of crystallization (T_p) as a function of logarithmic heating rate (logq). (D) Temperature difference (ΔT_p) versus heating rate (q). ΔT_p is the difference between the peak crystallization temperature of the annealed and cast samples.
