Abstract
The local environment issued from the phase decomposition in the Fe-30.8Cr-12.2Co alloy has been investigated by 57Fe Mössbauer spectrometry as a function of the ageing time and temperatures. In order to enable a precise determination of the different configurations, the analysis of Mössbauer spectra is improved using several different fitting models. It has been concluded that the phase decomposition in the Fe-30.8Cr-12.2Co alloy is spinodal and gives rise to the formation of a paramagnetic (α') phase and a magnetic (a) phase, with relative areas of ∼5% and ∼95%, respectively. The magnetic phase results from three main domains: an Fe-rich, a Cr-rich and a Co-rich with relative proportions of 9, 42 and 44%, respectively. The Cr content in the Fe-rich (α) phase is about 9 at.% Cr while that of the Cr-rich (a') phase is ranged between 71 and 80 at.% as a function of time and ageing temperature, which can be attributed to the kinetics of the phase decomposition. The (α') volume fraction estimated at about 28% is consistent with an isotropic decomposition where both (a) and (a') phases are strongly interconnected.
