Texture and Hardness in Wire Drawn [001] Copper Single Crystals

The crystallographic texture and Vickers hardness which develop during wire-drawing of [001] oriented copper single crystals have been studied experimentally as well by simulations. The experiments revealed orientation changes producing cross-shaped patterns in the {200} pole figures and important variations in the Vickers hardness across the diameter. Metallographic investigations showed the presence of deformation bands perpendicular to the initial 〈100〉 directions. By adopting a model for the velocity field inside the die, simulations have been carried out by using a Taylor type rate sensitive crystal plasticity model, including microscopic hardening. The simulated pole figures show the features of the experimental ones and the predicted stress levels correlate well with the measured hardness data.

The initial orientation has split into two equally strong symmetric orientations: (112)[111¯] and (112)[1¯1¯1]. Areas of identical orientation were band shaped and were called deformation bands. Up to 60% reduction, deformation occurs by slip on one plane (one from two possible) in two directions. This leads to the appearance of deformation bands with transition bands between them. Due to such deformation the initial orientation rotates around transverse direction towards the end-orientation {112}〈111〉. Due to rotation of the crystallographic lattice with deformation, the Taylor factor M changes as well, and it causes the activation of two not coplanar slip systems which stabilize the end-orientations {112}〈111〉. Such a sequence of the slip systems activation was concluded from the agreement of the calculated and experimental pole figures. The electron microscopy investigations showed that first shear bands formed due to the activation of these new slip systems.
