高熵合金
High-entropy alloysHigh-entropy alloys (HEAs) are a class of metallic materials characterized by the simultaneous presence of five or more principal elements, each in a near-equimolar ratio. This unique composition leads to high configurational entropy, which stabilizes the solid solution phase and results in exceptional mechanical properties, corrosion resistance, and thermal stability. / 高熵合金是一类金属材料的集合，其特征是同时存在五种或更多主要元素，且每种元素的比例接近等摩尔。这种独特的成分导致了高构型熵，从而稳定了固溶体相，并赋予其卓越的力学性能、耐腐蚀性和热稳定性。
