Ductility and Formability of Metals: A Metallurgical Engineering Perspective uses metallurgical, mechanical and physical principles and concepts to explain ductility while emphasizing the influence of material microstructure on damage mechanisms. Focusing on steel, aluminum, copper, titanium and magnesium alloys, the book examines the strain hardening behaviors of these metals and alloys, the influence of strain rate and temperature, and ductile fracture mechanics. Hot plastic deformation is covered with special consideration given to its interplay with recrystallization phenomena.

Other phenomena such as Dynamic Strain Ageing (DSA) and Adiabatic Shear Banding (ASB) are discussed, and metal working applications such as forging, extrusion and machining are included throughout. Methods for control of ductile cracks in metal parts resulting from rolling, forging, extrusion, drawing, and sheet metal forming are also outlined.

Giovanni Straffelini graduated in Materials Engineering at the University of Trento in 1989 and received his PhD in Metallurgical Engineering from the University of Padova in 1993. He currently teaches courses on ‘Metallic Materials Engineering’ and ‘Steelmaking and Foundry Technologies’ at the University of Trento. His research activity mainly concerns the sectors of tribology, mechanical metallurgy, plastic working of Al-alloys, powder metallurgy, topics on which he has published more than 200 scientific publications, mostly in international journals. He is also included in the World Ranking of Scientists, developed by Stanford University.
