The Mechanism of Influence of Non-Octahedral Slip on Rolling Texture Development in FCC Metals. Computer Simulation

Accepted30 Sep 1992


Simulation of the copper-type rolling texture development in FCC metals based on homogeneous slip under conditions of no constrains (Sachs-type model) is presented. Detailed analysis shows that, in fact, effective activation of a few (two or three, sometimes greater) independent slip systems occurs after reaching of some strain. These slip systems act by turns and may be essentially considered as acting simultaneously. Therefore, such extended description may be considered as a model which is intermediate between Taylor and Sachs ones. Taking these results into account, the characteristic features of main texture component development in copper under rolling have been studied by a computer simulation. Both octahedral, {111}, and cubic, {100}, slip planes are shown to act simultaneously in the process of the {112}111¯ component formation, but the action of only {111}11¯0 slip systems is characteristic for the {110}11¯2 component formation. The important role of the non-octahedral sip systems in plastic deformation processes in FCC metals of high staking-fault energy are also confirmed by the coincidence of model shear textures and experimental surface textures.
