High-Entropy Materials

This book draws on the latest research to discuss the history and development of high-entropy alloys and ceramics in bulk, film, and fiber form. High-entropy materials have recently been developed using the entropy of mixing and entropy of configuration of materials, and have proven to exhibit unique properties superior to those of conventional materials. The field of high-entropy alloys was born in 2004, and has since been developed for both scientific and engineering applications. Although there is extensive literature, this field is rapidly transforming. This book highlights the cutting edge of high-entropy materials, including their fundamentals and applications. Above all, it reflects two major milestones in their development: the equi-atomic ratio single-phase high-entropy alloys; and the non-equi-atomic ratio dual-phase high-entropy alloys.

Provides detailed information on the materials design, processing, and properties of high-entropy materials Elucidates the relationship between the micro- & nano-scale structures and properties of entropic materials Investigates the phase stability of high-entropy materials at elevated temperatures, including high-entropy super-alloys and ceramics Discusses the ultrahigh fracture toughness and Charpy impact toughness of high-entropy alloys at liquid helium and liquid nitrogen temperatures

Prof. Yong Zhang received his Ph.D. in Materials Science from the University of Science and Technology Beijing (USTB) in 1998. After two years of postdoctoral work at the Institute of Physics (IOP), Chinese Academy of Science (CAS), he then worked as a research fellow at the National University of Singapore (NUS) from 2000 to 2004 as part of the Singapore-Massachusetts Institute of Technology (MIT) Alliance (SMA). He was recruited to the USTB as a professor, working at the State Key Laboratory (SKL) for Advanced Metals and Materials.
In 2005, Dr. Zhang received an award from the Ministry of Education of China under the New Century Excellent Talents (NCET) in Universities program. His main research interest is the development of new materials in bulk, film, and fiber form using the high-entropy and materials-genome-initiative (MGI) strategies. He has published over 180 papers and received an award for outstanding contributions to natural science in 2010 for his research on strengthening and toughening bulk amorphous alloys, as well as an award for his work on deformation mechanisms of amorphous composites from Shanxi province in 2015.
