Abstract
In order to account for the differences observed between low and high temperature
deformation textures, the influence of slip or cross-slip on planes other than the
{111} is considered in FCC metals. The first set of possible new slip systems treated
is the {100}〈110〉. The dual single crystal yield surface is constructed using a novel
technique, and deformation textures are predicted for rolling and torsion using the
FC-RC model usually employed at room temperature. The {112} and {110}〈110〉
cross-slip systems are also considered. The rolling textures obtained when slip and
cross-slip or only cross-slip occur are presented. These two cases are first treated on
the assumption of a constant CRSS on all systems and then with the aid of a linear
latent hardening law, which only takes into account the interactions between colinear
systems.It is shown that the concurrent activation of both slip and cross-slip systems leads
to the presence of three main rolling components: i.e. the Cu, S and brass
orientations, in proportions that vary with the CRSS ratios of the different systems.
These results are in good agreement with experimental observations for high SFE
metals such as aluminum. Some torsion textures are also presented for the case when
both slip and cross-slip systems are activated. The trends observed in this case are
not as clear as in the case of rolling. However, the
