Features: In the 1980s, research found that if the component metals of an alloy are strictly proportioned according to the golden ratio, such as Al65Cu20F15, stable quasicrystals will form during the process of gradually cooling from liquid to solid. Quasicrystals are completely different from strict metal crystals and glasses, possessing their own unique properties, and thus hold broad application prospects. This book is written by the author based on summarizing the application results of cutting-edge research. The book is divided into five chapters: Chapter 1 primarily discusses the differences between quasicrystals and crystals and glasses; Chapters 2 and 3 introduce the electronic properties and atomic migration ability of quasicrystals, with thermal transport and surface properties as the focus of the respective chapters. The main arguments of these chapters lie in explaining why the peculiar properties of quasicrystals cannot be explained by metal theory or alloy theory. Chapter 4 mainly introduces the phase transformation of quasicrystals, the preparation of samples, and the pathways for large-scale production. Chapter 5 focuses on the current applications and potential application prospects of quasicrystals. References are listed after the preface and at the end of each chapter to assist readers who wish to delve deeper. At the end of the book, in the "Conclusion—The Dream Is Yet Unfulfilled," the author summarizes the history and current state of quasicrystal research, clarifies future research directions, and provides excellent guidance for readers.
