This book provides the latest developments in functional and engineering materials for defence applications. It contains a total of 20 book chapters in 2 proposed volumes: Vol. 1. Defence Functional Materials and Vol. 2. Defence Engineering Materials. All the book chapters are authored by leading scientists from the premier institutes, such as DRDO laboratory, DMSRDE, Kanpur, India, and edited by Drs. N Eswara Prasad, RJH Wanhill, and DK Setua. Both the authors and the editors are well known internationally for their seminal works in the Functional and Engineering Materials R&D and S&T. The principal purpose of this two-volume book is to provide the salient features of materials selection, synthesis, development and qualification for many a classical applications encompassing aero, naval and ground-based defence systems. They would surely act as valuable vade mecums for both active researchers, defence experts, post-graduate students, and faculty members who like to work and contributeto defence forces through research in areas such as defence materials, products, prototypes, sub-systems and systems that need cutting edge technologies and the latest and best materials and materials solutions.
