AI总结:

本研究通过测量七种高熵金属玻璃在初始、弛豫和晶态下的高频剪切模量与量热数据,揭示了剪切模量与结构弛豫缺陷浓度的内在联系,并证明相关规律受单一方程支配。

摘要:

我们在初始、弛豫和晶态下对七种高熵金属玻璃(HEMGs)进行了高频剪切模量和量热测量。结果表明,HEMGs的剪切模量与负责结构弛豫的缺陷浓度存在内在关联。在无结构弛豫时,玻璃的剪切模量温度系数等于母晶体的相应值。所有发现的规律均由单一方程支配。

英文摘要:

We performed high-frequency shear modulus and calorimetry measurements on seven high-entropy metallic glasses (HEMGs) in the initial, relaxed and crystalline states. It is shown that the shear modulus of HEMGs is intrinsically related with the concentration of defects responsible for structural relaxation. In the absence of structural relaxation, temperature coefficient of shear modulus of glass equals to that of the maternal crystal. All found regularities are governed by a single equation.
