Quantitative prediction of glass forming ability using a priori known parameters is highly desired in metallic glass development; however proven to be challenging because of the complexity of glass formation. Here, we estimate the number of potential metallic glasses (MGs) and bulk metallic glasses (BMGs) forming systems and alloys, from empirically determined alloy design rules based on a priori known parameters. Specifically, we take into account atomic size ratio, heat of mixing, and liquidus temperature, which we quantify on binary glasses and centimeter-sized BMGs. When expanding into higher order systems that can be formed among 32 practical elements, we reduce the composition space for BMG formation using developed criteria by 10⁶ times and estimate ∼3 million binary, ternary, quaternary, and quinary BMGs alloys.

有多少块大块金属玻璃？

在金属玻璃开发中，非常需要使用先验已知参数对玻璃形成能力进行定量预测。然而，由于玻璃形成的复杂性，事实证明具有挑战性。在这里，我们根据经验确定的基于先验已知参数的合金设计规则，估计潜在的金属玻璃（MGs）和块状金属玻璃（BMGs）形成系统和合金的数量。具体来说，我们考虑了原子尺寸比，混合热和液相线温度，它们在二元玻璃和厘米级BMG上进行了量化。当扩展到可以在32个实际元素中形成的高阶系统时，我们使用已开发的标准将BMG形成的组成空间减少了10 ⁶ 估计并估计约300万种二元，三元，四元和五元BMG合金。
