Carbon Distribution in Low-Temperature Isothermal Iron-Based Martensite and Its Tetragonality

“…The highest relaxation peak indicating to a largest dislocation density is obtained after holding at 150C, where the isothermal transformation is the most intensive. As shown in [45], this growth of S-K relaxation strength, 9%, is much higher than the increment of the isothermal martensite fraction, 4%, which could be another source of the increased dislocation density.…”
