Calorimetry heating curves of various metallic glasses or amorphous alloys. Primary exo (triangles) and main exo (circles) are shown on samples undergone (A) principal crystallization [46], (B) phase separation [50], (C) amorphous-to-quasicrystal (a-to-q) quasicrystallization [51], (D) liquid-to-quasicrystal (l-to-q) quasicrystallization [52], (E) short-range ordering [53] and (F) glaciation [3].
