Microscopic Shear Deformation Characteristics of the Lüders Front in a Metastable Austenitic Transformation-induced-plasticity Steel

To elucidate the mechanisms of deformation and a state plastic stability at front Lüders bands during tensile test, metastable austenitic transformation-induced plasticity (TRIP) steels with different dislocation densities ferritic were characterized via macroscopic-DIC-based stress–strain investigations scanning electron microscopy (SEM). A direct correlation between curves measured strain distributions in specimen indicated that represents transition region from instability to one stability, whereby general rule relating ∆
