Sommario/riassunto

This book focuses on the mechanical properties and permeability of coal, and the gas flow in coal seams. Based on coal permeability models, it establishes different models for coal seam gas, from the linear flow model to the gas–solid coupling flow model. It also provides the theoretical basis for the exploitation and safe production of coal as well as coal seam gas resources. As such, it is a valuable reference for researchers, advanced students and practitioners working in mining engineering and coalbed methane engineering. .

Sommario/riassunto

This book provides a comprehensive illustration to the superplastic forming/diffusion bonding (SPF/DB) technology developed over decades of research on titanium alloys, process modeling, and its application. SPF/DB technology plays key roles in building aviation components with complicated structures, with highly beneficial effects when well designed. With the ever-increasing demand on components with multiple layers, there is an urgent need for an updated assessment of traditional and modern SPF/DB processing methods. Success critically depends on making the most practical and effective choice of SPF/DB method for a given application. The book introduces titanium and titanium alloys, SPF/DB processing and its modeling, and applications for building typical single or multiple layer(s) structures. Particular attention is paid to illustrating the microstructure evolution



during SPF/DB processes. The information for making technical decisions about optimal choice of measurement and evaluation methods is also given in the book. Each chapter follows a focused and pragmatic format. Fully illustrated throughout, the book presents the state of the art in SPF/DB technology in a manner that makes it useful for engineers to improve the established forming processes and quality of components. This book is an essential reading material for industrial practitioners, academic researchers and postgraduates.
