从液体性质预测玻璃成形性

Prediction of glass formability from liquid properties

R. Dai, R. Ashcraft, A. K. Gangopadhyay, K. F. Kelton

摘要:

玻璃的形成是凝聚态物质领域中最有趣的现象之一。在理解和预测玻璃成形性方面已经做了相当大的努力。然而,先前的预测要求在可以执行预测之前首先制造玻璃。在这里,我们提出了一个新的预测公式只使用液体的性质。此外,我们还证明了液晶结构和晶体结构之间的相似性在决定玻璃成形性方面起着重要的作用。以前,只考虑成核和生长过程的动力学。

英文摘要:

Glass formation is one of the most interesting phenomena in the condensed matter field. Considerable effort has gone into understanding and predicting the glass formability. However, the previous prediction requires the glass first made before the prediction can be performed. Here, we propose a new prediction formula using liquid properties only. Moreover, we demonstrated that the similarity between liquid and crystalline structure plays an important role in determine the glass formability. Previously, only the kinetics of nucleation and growth processes have been considered.
