Temperature modulated DSC is used to study the fragility of three different bulk metallic glass forming liquids. Through applying various modulation frequencies, the dynamic glass transition shifts in temperature, allowing to determine the temperature dependence of the average relaxation time for each system. The resulting fragilities are compared with fragility investigations in literature obtained using thermo-mechanical analysis and the heating rate dependence of the calorimetric glass transition. Different methods to compare the data are evaluated and discussed.

通过调制 DSC 测定块状金属玻璃成型液的脆性


温度调制 DSC 用于研究三种不同的块体金属玻璃形成液体的脆性。通过应用各种调制频率，动态玻璃化转变温度发生变化，从而可以确定每个系统的平均弛豫时间的温度依赖性。将所得的脆性与使用热机械分析和量热玻璃化转变的加热速率依赖性获得的文献中的脆性研究进行比较。评估和讨论了比较数据的不同方法。
