Self-consistent modelling of TWIP steel during uniaxial tensile loading

Journal Article


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.
