Many of the properties that make common glass so valuable as a material can also be achieved in amorphous metals. The 'trick' is to avoid crystallization as the molten state is cooled. Recently, novel combinations of metals have been found to slow down crystallization enough to produce stable amorphous alloys. Developing these new materials depends on an accurate atomic level understanding of how crystallization is frustrated in glass-forming alloys. This project's aim is to use computer simulations to provide the first microscopic picture of the atomic order that stabilzes the amorphous alloys with regards to both crystallization and mechanical stress.

许多使普通玻璃作为材料如此有价值的特性也可以在非晶态金属中实现。"诀窍“是在熔融状态冷却时避免结晶。最近，已经发现新的金属组合足以减缓结晶以产生稳定的非晶态合金。开发这些新材料取决于对玻璃形成合金中结晶如何受阻的精确原子水平理解。该项目的目的是使用计算机模拟提供第一个原子顺序的微观图像，该原子顺序使非晶合金在结晶和机械应力方面稳定。
