前沿探讨:高熵合金(high-entropy alloys) 高熵合金(high entropy alloys),又叫高混乱度合金,多主元高功能合金(目前被定义为5~13元的多主元合金),是传统合金之外的另一个合金世界,由于其高温热稳定性、耐蚀性、高强度、高硬度、高抗氧化性质、优异的磁电性能等,为金属材料开创了一个新的领域,成为一种极具发展...
Forthe past decade and a half, however, a new alloying strategy that involves the combination ofmultiple principal elements in high concentrations to create new materials called high-entropy alloys has been in vogue. The multi-dimensional compositional space that can be tackled with this approach ...
一、高熵合金粉末简介(一)定义与组成高熵合金(High-entropy alloys)简称 HEA,是利用五种或五种以上,等量或大约等量的金属形成的合金,每个元素原子都随机分布,抑制了脆性化合物的生成,因此高熵合金有着很强的韧性。与只以一种金属元素为主,添加少量其他元素的传统合金相比,高熵合金很可能拥有更多优异的性能,比如高...
金属高熵材料(Metallic high-entropy materials, HEMs),又称高熵合金(high-entropy alloys, HEAs),多成分合金(multicomponent alloys),多主元合金(multi-principal element alloys),组成复杂合金(compositionally complex alloys, CCAs),无基元合金(baseless alloys, BAs)等自2004年问世以来得到科学家的广泛关注与研究。
High-entropy alloys (HEAs) are single-phase alloys containing five or more metallic elements with equal or close atomic ratios.

High-entropy alloys (HEAs) are presently of great research interest in materials science and engineering. Unlike conventional alloys, which contain one and rarely two base elements, HEAs comprise multiple principal elements, with the possible number of HEA compositions extending considerably more than ...
Clearly,the vast majority of possible alloys have never been investigated,and they are mainly multi-component high-entropy alloys located in the center of multicomponent phase diagrams,as indicated in Fig.1.3.How Many Possible Phases Are There in a Multicomponent Alloy?The Gibbs phase rule p þ...
