Etude de l'interaction lacune–carbone dans l'alliage Ni-20% at. Fe par la méthode de l'anisotropie magnétique induite

Abstract: On a étudié l'élimination des lacunes retenues par trempe dans un alliage Ni‐20% at. Fe, contenant du carbone en solution solide interstitielle. L'étude a été faite en suivant l'établissement de l'ordre directionnel, par des mesures d'anisotropie magnétique. On observe un ralentissement de la migration des lacunes, qui résulte de leur piégeage sur les interstitiels de carbone; cet effet est en désaccord quantitatif avec le modèle de Lomer; il est, par contre, très bien décrit par un modèle qui tient compte de … Show more

“…The IMA density is proportional to the carbon concentration [9]. That property has been used to determine nondestructively the quantity of carbon in these alloys [10]. Also very good agreement has been found between the jump frequency as deduced from the experiments, and that calculated from the carbon diffusion coefficients [11].…”

“…Hence, the two should not be treated the same way. In the binary FCC Fe-C system, it was found that the interstitial carbon atoms form interstitial-vacancy (i-vac) complexes [43,44]. However, no explanation could be found how these complexes increased the self-diffusion of iron except for the dilation of the matrix due to interstitial carbon atoms [45].…”
