✦ Synopsis

Research in the field of high-entropy materials is advancing rapidly. High-Entropy Materials: Advances and Applications focuses on materials discovered using the high-entropy alloys (HEA) strategy. It discusses various types of high-entropy materials, such as face-centered cubic (FCC) and body-centered cubic (BCC) HEAs, fi lms and coatings, fi bers, and powders and hard-cemented carbides, along with current research status and applications

• Describes, compositions and processing of high-entropy materials.

• Summarizes industrially valuable alloys found in high-entropy materials that hold promise for promotion and application.

• Explains how high-entropy materials can be used in many fi elds and can outperform traditional materials.

This book is aimed at researchers, advanced students, and academics in materials science and engineering and related disciplines.
