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,成为一种极具发展潜力的新兴材料。若取80种金属中的13种元素...
For the past decade and a half, however, a new alloying strategy that involves the combination of multiple 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 ...
High-entropy alloys (HEAs) are alloys with five or more principal elements. Due to the distinct design concept, these alloys often exhibit unusual properties. Thus, there has been significant interest in these materials, leading to an emerging yet exciting new field. This paper briefly reviews so...

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...
High-entropy alloys_Easo P. George 下载积分: 1500 内容提示: Since the Bronze Age, humans have been altering the properties of materials by adding alloying elements. For example, a few percent by weight of copper was added to silver to produce sterling silver for coinage a thousand years ago...
High-entropy alloys (HEAs) have recently become a vibrant field of study in the metallic materials area. In the early years, the design of HEAs was more of an exploratory nature. The selection of compositions was somewhat arbitrary, and ... T Ming-Hung - 《Entropy》 被引量: 7发表: 2016...
