Abstract The martensite microstructure, amount of retained austenite and itscarbon content in 40CrNiMo steel quenched at various conditions have been in-vestigated by using transmission Mossbauer spectroscopy at room temperature. It wasshown that the toughening effect of high-temperature quenching and the thermome-chanical quenching has little correlation with the amount of retained austenite.
