摘要：

20世纪90年代，针对与传统合金设计理念大相径庭的多主元合金的研究悄然展开。2004年，高熵合金的概念正式被提出，这类合金所具备的耐高温、耐磨、耐腐蚀、抗辐照等性能远非传统合金体系可比。目前，高熵合金的研究已经成为合金领域的研究热点，研究过程中应用到溶液热力学理论、相平衡理论等物理化学知识。本文对多种应用材料拟人化，以成人礼的形式，呈现四类高熵合金的研究近况。

Abstract:

In the 1990s, a revolutionary approach to alloy design emerged, diverging from traditional methods, known as multi-principal alloys. A decade later, the concept of high entropy alloys (HEAs) took center stage, showcasing properties such as exceptional high temperature resistance, wear resistance, corrosion resistance, and radiation resistance that far surpassed those of conventional alloys. Today, HEA research has become a focal point in the field of alloys. This paper presents the research status of various materials through a captivating coming-of-age ceremony, personifying different application materials. Moreover, it delves into the physical and chemical knowledge underpinning the research process, including solution thermodynamics theory and phase equilibrium theory. Through the lens of a coming-of-age ceremony, the paper highlights the distinctive characteristics and research progress of four intriguing types of high entropy alloys.
