Ductility and Formability of Metals: A Metallurgical Engineering Perspective

by Giovanni Straffelini

Overview

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. - Provides an overview on the plastic deformation behavior and ductile fracture of steel, aluminum, copper, titanium and magnesium alloys - Illustrates the influence of microstructure on yield behavior, strain hardening of metals, and the influence of strain rate and temperature - Covers the role of the strain hardening coefficient (n), strain rate index (m), Dynamic Strain Ageing (DSA), and Adiabatic Shear Banding (ASB) - Metalworking applications are provided throughout, including forging, rolling, extrusion, wire drawing, sheet metal forming and machining
