这本书提供了在高熵合金（HEA）领域的艺术的当前状态的完整审查。传统的合金设计方法是选择一种主元素，少量添加元素，以改善合金的性能。2004年，J.W. Yeh教授和他的团队首次报道了一种合金设计的新方法，该方法涉及以等原子或近等原子比例混合元素，以形成没有单一主元素的多组分合金。这些合金预计具有高的构型熵，因此被称为“高熵合金”。HEAs具有广泛的结构和性能，可用于结构、电气、磁性、高温、耐磨、耐腐蚀和抗氧化部件。由于其独特的性能，高熵合金引起了学术界和技术界的广泛关注。本书介绍了目前在该领域的基本知识，各种合金系统的频谱及其研究至今的特点，目前的重点领域，以及该领域未来的研究和技术应用范围。
This book provides a complete review of the current state of the art in the field of high entropy alloys (HEA). The conventional approach to alloy design is to select one principal element and add elements to it in minor quantities in order to improve the properties. In 2004, Professor J.W. Yeh and his group first reported a new approach to alloy design, which involved mixing elements in equiatomic or near-equiatomic proportions, to form multi-component alloys with no single principal element. These alloys are expected to have high configurational entropy and hence were termed as "high entropy alloys." HEAs have a broad range of structures and properties, and may find applications in structural, electrical, magnetic, high-temperature, wear-resistant, corrosion-resistant, and oxidation-resistant components. Due to their unique properties, high entropy alloys have attracted considerable attention from both academics and technologists. This book presents the fundamental knowledge present in the field, the spectrum of various alloy systems and their characteristics studied to date, current key focus areas, and the future scope of the field in terms of research and technological applications.
