Modelling of Texture Development and Deformation Mechanisms in a Ti20V Alloy Using a Self Consistent Polycrystal Approach

Abstract

Modellisations of the deformation texture development in a Ti20V alloy (20 volumic % Vanadium) during rolling have been carried out using the viscoplastic self consistent model of Molinari and Toth (1994). The model parameters and the slip and twinning systems were identified from experimental data. The experimental texture evolution is well reproduced with only a small contribution of the twinning activity.
