Abstract

X‐ray diffraction was used to track the evolution of texture in a fully recrystallized Fe–24Mn– 3Al–2Si–1Ni–0.06C TWinning Induced Plasticity steel subjected to uniaxial tensile testing. The bulk texture measurements returned the characteristic double fiber for fcc materials with a relatively stronger k111i fiber and a weaker k100i fiber parallel to the tensile axis. The Visco‐Plastic Self‐Consistent model was used to simulate the macroscopic stress–strain response as well as to track the evolution of the bulk crystallographic texture by detailing the contribution of slip and twinning when latent hardening effects are excluded or included. The simulations revealed the dominant role of slip and the limited volume effect of twinning on the overall development of the bulk texture. The correlation between the latent hardening effects and the employed grain interaction scheme is highlighted.
