多主元素合金（Multi-Principal Elements Alloy，MEAs）是一种多元素等摩尔比混合的高熵合金，它的出现给材料科学家和物理学家带来了巨大的挑战。例如，在一个实施例中，如何预测高熵相的形成和设计合金。在本文中，我们提出了一些指导方针，预测相形成，使用热力学和拓扑参数的组成元素。该准则与现有准则一起将为MEA和HEAs的组成设计以及基于组成-结构-性能关系的性能优化铺平道路。
With multiple elements mixed at equal or near-equal molar ratios, the emerging, high-entropy alloys (HEAs), also named multi-principal elements alloys (MEAs), have posed tremendous challenges to materials scientists and physicists, e. g., how to predict high-entropy phase formation and design alloys. In this paper, we propose some guidelines in predicting phase formation, using thermodynamic and topological parameters of the constituent elements. This guideline together with the existing ones will pave the way toward the composition design of MEAs and HEAs, as well as property optimization based on the composition-structure-property relationship.
