Effects of annealing condition and heating rate on enthalpy relaxation, shadow glass transition, and crystallization for the sample Y₆₃Zr₂Cu₂₀Al₁₅ MG. (A), (B), and (C) show the heat flow diagrams of the as-cast sample, the sample annealed at 433 K for 30 min, and the sample annealed at 563 K for 30 min, respectively. They have the same horizontal coordinate, i.e., heating from 400 K to 740 K. The heating rates are both from 100 K/s to 6000 K/s.
