Abstract

Mössbauer effect studies have been carried out to investigate the 475‡C decomposition of binary Fe-Cr alloys. Spectra of Fe-24 and Fe-60 at. pct Cr were obtained in the as-quenched and annealed conditions. When the Fe-60 at. pct Cr alloy was aged at 475‡C for up to 30 hr, the spectrum broadened but showed no signs of resonant absorption at energies expected for the equilibrium two-phase alloy. This data is interpreted as an indication that initial decomposition produces fluctuations about the average composition, consistent with expectations for spinodal decomposition as would be predicted for this alloy at 475‡C. By contrast, the Fe-24 at. pct Cr alloy lies outside the spinodal at 475‡C and gives Mössbauer spectra consistent with decomposition via nucleation and growth. Limited success was achieved in attemptsto synthesize the observed spectra using simple models of the hyperfine spectra and the theory of spinodal decomposition.
