Abstract
The isotope effect of carbon diffusion in dilute iron silicon alloys containing 28Si and 30Si has been measured below room temperature using the Dis accommodation technique. The time dependence of the reluctivity has been analyzed in terms of two relaxation processes which are due to the reorientation of carbon interstitials in Fe-Fe and Fe-Si sites respectively. The ratio of the relaxation times of the two carbon isotopes 13C and 12C τ13/τ12 is 1.037 for the former and 1.007 for the latter process in the Fe+28Si alloy. The ratios of the relaxation times of the same carbon isotope 12C contained in a dilute Fe+30Si and in a dilute Fe+28Si alloy respectively τ30/τ28 are 0.995 and 1.020 for the two processes mentioned. These results demonstrate clearly the many body aspects of the diffusional process. © 1969.
