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...
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...
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...

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 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...

This book provides a systematic and comprehensive description of high-entropy alloys (HEAs). The authors summarize key properties of HEAs from the perspective of both fundamental understanding and applications, which are supported by in-depth analyses. The book also contains computational modeling in ta...
High-entropy alloys (HEAs) have emerged as an important class of materials in the last one decade with immense potential both at the level of fundamental understanding and also in terms of applications. This chapter deals with the basic concepts that underpin this new class of alloys. It ...
of HEAs can be a single phase or multiphases, and traditional physicalmetallurgy principles have been applied to develop a variety of HEAs, including high-entropystainless steels, high-entropy superalloys, high-entropy refractory alloys, high-entropy light-weightalloys, high-entropy oxides, high-...
