Fundamentals of Sintering

This book provides cutting-edge knowledge on the theory and modelling of solid-state sintering. It includes new knowledge on 3D microstructural evolution obtained by computer simulations and nano/micro-tomography, as there has been significant progress in the basic sintering theory in the last 20 years. This book presents the fundamental principles related to sintering phenomena, with a focus on understanding the thermodynamic driving forces. Readers can gain insights by examining how atomic-level interactions lead to micro-scale structural changes, which in turn influence densification and deformation processes at the macro-scale. This book is a completely new and easy-to-understand textbook for graduate students, researchers, and engineers in ceramic technology and powder metallurgy. It aims to help them understand fundamental theories essential for developing new materials and improving processing methods efficiently.

Provides cutting-edge knowledge on the theory and modeling of solid-state sintering Presents new insights into sintering phenomena in multiscale: atomic, microscopic, and macroscopic scales Includes advances in the rapidly expanding field of 3D microtomography and simulation

Autorentext

Fumihiro Wakai is a professor emeritus at Tokyo Institute of Technology (now Institute of Science Tokyo), Japan. He was a director of the Laboratory for Materials and Structures, Institute of Innovative Research, Tokyo Institute of Technology, and is now working at the National Institute of Materials Science. Prof. Wakai has received an M.S. degree in Physics and a doctoral degree in Engineering from Kyoto University, Japan. He has published over 240 scientific papers. His early research was concerned with the superplasticity of ceramics. He then worked on modelling and theory of sintering, which is regarded as deformation induced by the motion of a huge number of particles from the mechanical point of view. He is a fellow of the American Ceramic Society, the Ceramic Society of Japan, and the World Academy of Ceramics.
