论文摘要
通过将原子模拟与单个原子啤酒花的详细分析相结合，我们表明碳在二进制Fe-C玻璃中的扩散表现出很强的（反）相关性，并且在很大程度上取决于当地环境。局部碳浓度较高会导致原子迁移率较慢。我们的结果有助于解释Fe-C（和其他类似的金属类玻璃杯）对结晶的稳定性提高，并且碳浓度的增加。
By combining atomistic simulations with a detailed analysis of individual atomic hops, we show that the diffusion of carbon in a binary Fe-C glass exhibits strong (anti-)correlations and is largely determined by the local environment. Higher local carbon concentrations lead to slower atomic mobility. Our results help explain the increasing stability of Fe-C (and other similar metal-metalloid glasses) against crystallization with increasing carbon concentration.
