Deformation Processing of High Entropy Alloys provides a comprehensive examination of the unique mechanical properties and advanced processing techniques associated with high entropy alloys (HEAs). Beginning with a clear introduction to the fundamentals of HEAs, the book distinguishes these innovative materials from conventional alloys, highlighting their distinctive microstructural evolution and deformation mechanisms. Readers gain insight into the influence of alloy composition and crystal structures, specifically focusing on FCC- and BCC-based HEAs, as well as the critical roles of stability, metastability, and thermomechanical treatments in shaping their performance. Further, the book delves into a variety of deformation processing methods, including solid-state techniques and additive manufacturing, offering practical guidance for researchers and engineers. Modeling and simulation strategies are explored, enhancing understanding of HEA behavior under different conditions.

Nanocrystalline materials exhibit exceptional mechanical properties, representing an exciting new class of structural materials for technological applications. The advancement of this important field depends on the development of new fabrication methods, and an appreciation of the underlying nano-scale and interface effects. This authored book addresses these essential issues, presenting for the first time a fundamental, coherent and current account at the theoretical and practical level of nanocrystalline and nanocomposite bulk materials and coatings. The subject is approached systematically, covering processing methods, key structural and mechanical properties, and a wealth of applications. This is a valuable resource for graduate students studying nanomaterials science and nanotechnologies, as well as researchers and practitioners in materials science and engineering.
