Fe-rich border and activation energy of phase decomposition in a Fe-Cr
alloy
   [PDF]

S. M. Dubiel, J. Zukrowski
Concentration of Cr in the Fe-rich alpha-phase, x, resulted from a phase decomposition caused by an isothermal annealing at T = 415 and 450 C of a non-irradiated Fe-Cr14 EFDA sample and that of a He-ions irradiated one annealed at 415 C was determined using the technique of the conversion electron M\"ossbauer spectroscopy (CEMS). The x-value in the latter was by 2.7 at% higher than the one in the non-irradiated counterpart. The activation energy for the phase decomposition in the non-irradiated sample was determined as equal to 216 kJ/mol. In the irradiated sample its value was by ~2.9 kJ/mol higher.
