Hot Cracking Phenomena in Welds II

This is the second in a series of compendiums devoted to weld hot cracking phenomena, where this subject has been further scrutinized, bringing to bare the most current thoughts on this complex and diverse subject. With 22 technical papers in total, this book is divided in such a way that specific classifications of hot cracks are examined in detail, including solidification, liquation, and ductility dip cracking. The first chapter looks at solidification cracking theory, applying the most modern approaches to modelling weld solidification. Also provided here is a comprehensive review of cracking models. This is followed by two chapters characterizing solidification cracking behaviour for specific alloy systems: ferrous plus nickel-based alloys and aluminium alloys, respectively. The fourth chapter considers liquation cracking in ferrous alloys, and the fifth examines ductility-dip cracking. For engineers and scientists involved in materials research and development, this book provides both new insight and a broad overview of hot cracking phenomena in welds. The contributions additionally give numerous individual solutions and helpful advice for welding engineers to avoid hot cracking in practice. Furthermore, this book can serve as a useful teaching aid for upper level metallurgical, welding and mechanical engineering students.
