Deformation processing Exploit ‘plasticity’ – ability of solids to deform and flow without deterioration of properties Processing entirely in solid state Little material wastage Requires large forces high machine tooling costs large production volumes may be required to justify costs Processes include bulk flow, simple shearing, or compound bending

Stresses in Metal Forming Stresses to plastically deform the metal are usually compressive Examples: rolling, forging, extrusion However, some forming processes Stretch the metal ( tensile stresses) Others bend the metal ( tensile and compressive) Still others apply shear stresses
