Cyclic Textures in Aluminium Wires

Three-dimensional orientation distribution functions were calculated from neutron diffraction pole figures of unwoundcylinders taken at different distances from the centre of cold drawn Al-wires. Their features change fromthe axially symmetric type at the very centre of the wire towards a texture near to the rolling type at the surface.Relations between the three-dimensional function and ordinary fibre texture pole figures were used to study thedependence of the textures on certain processing variables for cold drawn as well as recrystallized wires.
