Abstract
In the present work, deformation mechanisms have been studied by evaluating texture and microstructure under cold rolling for medium Mn containing Fe-14Mn-0.5C-3.5Al twinning induced plasticity (TWIP) steel. Rolling has been performed up to true strain ∼2.3. Microstructural features reveal that deformation takes place by twinning. Texture evolution shows α-fiber type texture with a continuous α-fiber up to very large strains. Experimentally observed deformation micro-mechanisms have been verified with the visco-plastic self-consistent (VPSC) simulation. Effects of twin volume fraction in texture evolution also been studied by incorporating volume transfer scheme in the VPSC simulation. Simulation results show very good agreement with the experimental results.
