Abstract
-
The Visco-Plastic (VPSC) and Elasto-Plastic (EPSC) Self-Consistent models were applied to
simulate the macroscopic stress-strain response and the evolution of crystallographic texture
during the tensile loading of a fully annealed Fe-24Mn-3Al-2Si-1Ni-0.06C TWIP steel. Bulk
texture measurements acquired by X-ray diffraction were used to validate the modelling
results. Various modelling constructs were employed to assess the contribution of twinning and
latent hardening to the texture evolution. The simulations revealed the dominant role of perfect
slip and the limited effect of twinning on texture development as well as a possible role for
latent hardening. Comparison between the texture predictions of the VPSC and EPSC models
underscored the correlation between the latent hardening effects and the employed grain
interaction scheme.
