Abstract
”Tis but thy name that is my enemy” Shakespeare, Romeo and Juliet.
The term “High Entropy Alloys” (HEA) has become very popular in the alloy development community in recent years. The term is specific to a subset of alloy composition space in which a solid solution is stabilized by a high configurational entropy due to a large number of equimolar components. Numerous research papers contain the term, yet on examination much of the work is not in fact on alloys stabilized by the entropy component of the Gibbs energy. This paper discusses the reasons why the term should be used only for alloys in which entropy is the dominant thermodynamic parameter, and more appropriate terms such as multi-principal element alloys should be used for the vast majority of research papers on this topic.
期刊介绍：
The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials.
