In order to check conventional results obtained by the traditional experimental methods, the concentration and temperature ranges of the miscibility gap are closely examined by Mössbauer spectroscopy. The present result does not support the earlier Williams’ result that the upper limiting temperature of the miscibility gap is about 830 K, but proposes that it is about 950 K. The proposed miscibility gap is well expressed by the regular solution treatment on the whole, and lies over the concentration range from 10 to 86 at%Cr at low temperatures around 750 K.
