摘要: Conversion electron Mossbauer spectroscopy allows the resolution of all components in spectra 100 pct retained austenite for varying carbon contents (>6.5 at. C). An off-stoichiometry ordered structure, Fe8Ci1−y, is proposed which confirms interstitial repulsion y iron. Transmission used to follow nonisothermal kinetics concomitant clustering and ordering processes during aging first stage tempering 8.5 8 iron martensite. Activation energies 75 ∓ 2.5, 74 1.5, 121.5 1.5 kJ/mole are observed. The synergy between within frame multiplet model emphasized. e- or η-carbide obtained by analyzed be Fe2.4C.
