Description
The 2009 Mordica Lecture presents an overview of the variety of structural evolutions and texture formations in drawing metals with face-centered cubic (fcc), body-centered cubic (bcc), and fcc- viz. bcc-based two-phased materials. It shows how directionality of structure and texture can be controlled by suitably chosen drawing conditions. This enables understanding of the strength anisotropy of drawn copper tubes, the orientation effect on shape-memory elongation of copper and titanium alloys, the flow stress changes of steel wire when changing strain path, and the resistance to fatigue fracture and delamination of pearlitic steel wire.
