Mechanical Aspects of High Entropy Alloys: Fundamentals, Modeling, and Properties is structured by the sub-category of mechanical behavior, covering almost all key themes in this area, including strength, ductility, creep, fracture, fatigue, small-scale mechanical behavior, strengthening mechanisms, deformation mechanisms, and serrated plastic flow. For each individual topic, the focus is geared towards the distinctive characteristics of high-entropy alloys (HEA).
This book is a valuable resource to advanced students and researchers in need of an entry point to the field of HEAs, and experienced academic and industrial researchers who wish to either deepen their knowledge or gain inspiration during the process of their HEA research.
- Provides in-depth information on the mechanical behavior of high-entropy alloys for both newcomers and experienced researchers
- Highlights the distinctive characteristics for each aspect of mechanical behavior
- Introduces the fatigue, creep, and fracture properties of HEAs
- Discusses future scientific issues and challenges
Advanced students, engineers, researchers and R&D professionals working in the fields of materials science, engineering, and biomedical engineering. Industrial practitioners in aerospace, energy, nuclear, and transportation sectors.
