Abstract 57Fe Mössbauer spectroscopy is, with13C NMR, the only technique enabling to follow the redistribution of interstitials occuring during low temperature aging in ferrous martensite and responsible for the formation on the carbides obtained by tempering. We report the isochronal aging of martensite from as-quenched samples of high carbon content in order to follow the kinetics, all over the temperature range from 78°K to 400°K, thus covering the aging and the first stage of tempering as well. X-ray diffraction analysis is done in parallel for all temperatures above ambient. The results sustain the fact that one unique process is involved, leading to the precipitation of ∈ or ν carbide by stress-induced mechanism.
