CRYSTAL SPIN IN 2-SITES SELF-CONSISTENT MODELS - FROM KINEMATICS TO KINETICS

In the current presentation we deal with the interpretation of texture s of two-phase co-deformable materials. We use a 2-sites visco plastic self consistent (2S-VPSC) model computing the spin of each phase thro ugh an empirical law describing spin sharing between both phases. Cu-F e and Ag-Ni composite materials represent two kinds of two-phase mater ials that have been extensively studied in the past. Neutron and X-ray texture measurements of rolled, free compressed and extruded samples are shown and analyzed in light of the model. Many of the particularit ies shown by both materials are explained and a general discussion of the model is provided. (C) 1997 Elsevier Science B.V.
