Abstract

The atomic arrangements in Fe-C martensite, especially the interstitial carbon positions have been discussed utilizing57Fe Mössbauer spectroscopy and13C and57Fe spin-echo NMR measurements. The experimental result is well explained by the model of two interstices occupancy of carbon in the bct martensite. Especially, the spin-echo spectra by13C nuclei showed that two main lines first appear and clear satellite lines gradually rise during the aging at 323K, suggesting the carbon jumps from the tetrahedral to the octahedral interstices and further movements to form a local ordered arrangement.
