Corrosion Resistance Behaviour of Metallic Materials Subjected to Laser Shock Peening

Laser shock processing (LSP) is a new and promising surface treatment technique for improving the fatigue durability, corrosion, wear resistance and other mechanical properties of metals and alloys. During LSP, the generated shock wave can introduce a deep compressive residual stress into the material, due to its high-pressure (GPa-TPa), ultra-fast (several tens nanoseconds), ultra-high strain-rate and high-energy. The overall properties and behavior of metal materials subjected to LSP were significantly improved because a refined surface layer was successfully obtained. Nevertheless, up to now, a clear scenery between micro-structure and macro-property of the refined surface layer, especially formation of sub-micrometer grains from coarse grains during severe plastic deformation, is still pending. Therefore, the basic studies of the underlying mechanism for grain refinement by ultra-high strain-rate presented in this book becomes more and more crucial.

This book explores the various casting and modelling activities related to metallic alloy systems. The book provides results of research work conducted by experts from all over the globe to add to the research community in the era of the casting process and modelling.

This book examines archaeometallurgy and the preservation of ancient materials for cultural heritage. Through understanding the internal structures of relevant ancient materials, their chemical composition, resistance, hardness, etc., their conservation can be more effectively addressed. Preserving cultural artifacts, such as those from border sites, funerary contexts (burials), railway lines, ceremonial sites and road infrastructure, is necessary to provide perspective to a culture’s trajectory.
