摘要：

Issues pertinent to the miscibility gap at 800 Kin a Fe73.7Cr26.3 alloy viz. the kinetics of the phase decomposition and borders of the latter were investigated by means of the Mossbauer-effect spectroscopy. The kinetics was revealed to well follow the Johnson-Mehl-Avrami-Kolgomarov equation testifying to a nucleation and growth mechanism underlying the decomposition. A solubility limit of Cr in the Fe matrix was determined to be 17.3(6) at% and that of Fe in the Cr matrix was found as equal to 18.5(9) at%. The results obtained have been compared with various theoretical predictions.
