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.
- Physical chemistry,
- High entropy alloys,
- Mixed entropy
