Abstract Ce69Al10Cu20Co1 metallic glass was fully annealed to its metastable equilibrium supercooled liquid (MESL) state at a temperature below the calorimetric glass transition, i.e., sub-Tg, and quenching/cryogenic combined treatment (Quenching + CT) was subsequently manipulated in liquid nitrogen. The evolution of glass transition, specific heat capacity (Cp) and enthalpy change (ΔH) were investigated by differential scanning calorimetry (DSC). Rejuvenation phenomenon on the perspective of energy level was found compared with the relaxed state of the sample. The evolution of the structural states, including the free volume, internal stress and atomic clusters, that caused by the quenching process and subsequent cryogenic treatment is discussed and acted as the physical interpretation to the relaxation-to-rejuvenation transition.

通过在亚 Tg 下进行淬火/低温处理，Ce 基金属玻璃的弛豫-再生转变

摘要 Ce69Al10Cu20Co1 金属玻璃在低于量热玻璃化转变的温度下完全退火到其亚稳态平衡过冷液体 (MESL) 状态，即亚 Tg，然后在液氮中进行淬火/低温联合处理 (Quenching + CT)。通过差示扫描量热法 (DSC) 研究玻璃化转变、比热容 (Cp) 和焓变 (ΔH) 的演变。与样品的松弛状态相比，从能级的角度发现了回春现象。讨论了由淬火过程和随后的低温处理引起的结构状态的演变，包括自由体积、内应力和原子团簇，并作为松弛到恢复转变的物理解释。
