The Formation of Complex Microstructures After Different Deformation Modes in Advanced High-Strength Steels

The microstructure of transformation induced plasticity (TRIP) and dual phase (DP) multiphase steels after stamping of an industrial component at different strain levels was investigated using transmission electron microscopy. The TRIP steel microstructure showed a more complex dislocation substructure of ferrite at different strain levels than DP steel. The deformation microstructure of the stamped parts was compared to the deformation microstructure in these complex steels for different “equivalent” tensile strains. It was found that the microstructures are similar only at high levels of strain (>10 pct) for both steels.
