本文报道了多种金属玻璃的玻璃化转变温度（Tg）与其二元相图中两种主要成分的共晶温度或过晶温度相关联。关联式表明，镁合金的Tg主要取决于其两种基本组分的溶剂，这两种基本组分的组成接近于二元相图中的低共熔点和包熔点，是非晶结构中最薄弱的环节。研究结果对于理解镁合金的结构和玻璃化转变以及预测和设计具有理想Tg的金属玻璃具有重要意义。(C)2014爱思唯尔有限公司版权所有。
We report that the glass transition temperature (T-g) of a variety of metallic glasses (MGs) correlates with the eutectic or peritectic temperature of two main components corresponding stoichiometric proportion in their binary phase diagram. The correlation suggests that the T-g of MGs is mainly determined by their solvent of two base components, which have composition close to the eutectic and peritectic points in the binary phase diagram and the weakest link in amorphous structure. The results have implications for understanding the structure and glass transition in MGs and for predicting and designing metallic glasses with a desirable T-g. (C) 2014 Elsevier Ltd.
