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.

在无定形金属中也可以实现许多使普通玻璃如此有价值的普通玻璃的特性。 “窍门”是避免结晶，因为熔融状态被冷却。最近，已经发现金属的新型组合可以减慢结晶，以产生稳定的无定形合金。开发这些新材料取决于准确的原子水平了解如何在形成玻璃合金中如何挫败结晶。该项目的目的是使用计算机模拟来提供原子秩序的首次微观图片，该图片稳定在结晶和机械应力方面。
