Résumé
A partir de la spectrométrie Mössbauer, on propose une méthode pour déterminer quantitativement le taux d'austénite retenu dans des aciers alliés avec des éléments carburogènes. On élimine ainsi l'effet parasite des carbures paramagnétiques contenant du fer, à l'aide de procédés auxiliaires tels que traitements thermiques et analyse chimique. La méthode semble appropriée pour l'examen de la formation, la transformation et la stabilisation de l'austénite.
Abstract
A method based upon Mössbauer spectroscopy is proposed for the quantitative determination of the retained austenite in steels alloyed with carbide forming elements. By means of this method, the disturbing effect of the paramagnetic carbides containing iron can be eliminated. The proposed method makes use of some supplementary procedures as for example appropriate heat treatments and chemical analysis. The method seems to be suitable for the examination of formation, transformation and stabilization of austenite.
