Amorphous Alloys and High-entropy Materials
Introduction
This book mainly introduces two new structured materials, namely amorphous alloy and high-entropy material. There are 7 chapters in the book: Chapter 1 is an overview of amorphous alloys, which mainly introduces the emergence and development of bulk amorphous alloys and the thermodynamic and kinetic basis of amorphous alloy formation; Chapter 2 introduces the glass-forming ability, that is, the difficulty of glass-forming state of alloy; Chapter 3 is about the properties of bulk metallic glass, mainly introduces the problems that need to be overcome when it comes to the industrial application; Chapter 4 “Process of Amorphous Alloy”, mainly introduces the forming and processing technology of amorphous alloy in practical engineering applications; In chapter 5, the preparation and fatigue behavior of low-cost amorphous alloys are introduced. A series of low-cost amorphous alloys for industrial application is developed by using low-cost high-pressure die casting method and industrial grade materials supplemented with trace rare earth element (Y); Chapter 6 is an overview of high-entropy materials, introducing some work on high-entropy alloys developed based on amorphous alloys in recent years; Chapter 7 introduces the latest development of high-entropy materials, including process-oriented and performance-oriented design of high-entropy materials, including machine learning, high-throughput computing, and high-throughput experiments. Several promising high-entropy materials have been discovered so far.
This book is suitable for scientific research and engineering technicians, postgraduates, or senior undergraduates in the fields of materials science, condensed matter physics, and amorphous physics, and can also be used as an elective textbook for related majors.
