Figure 1

CDB ratio spectra for pearlite (PER), martensite (M) and bainite formed at different temperatures (B220, B250 and B300) obtained after different heat treatments (see Table 1 for details) from the studied steel, normalized by the CDB spectrum of a pure annealed Fe reference sample. The normalized CDB ratio curves for C, Si, Cr and Mn are shown for comparison. The suffix ‘+6d’ indicates that the sample was held at the transformation temperature during 6 days after completion of bainite transformation.
