SHORT-RANGE ORDER IN Fe-Cr ALLOYS IRRADIATED WITH ELECTRONS AT LOW TEMPERATURES AND Cr SOLUBILITY IN α-IRON NEAR 270 K

Chromium has limited solubility in a-iron. It is shown that unsaturated Fe-Cr alloys should demonstrate short-range ordering (i.e. tendency to neighboring of Fe and Cr atoms). The type of short-range ordering in several Fe-Cr alloys is revealed from the data on the recovery of residual electrical resistivity after low temperature electron irradiation at sufficiently low temperatures. The combined consideration of the data on short-range ordering and chromium solubility at 570 K (Scr. Mater. 2014 v. 74, p. 48 and ibid 2016 v. 122, p. 31) gives the confidence interval for the solubility limit near 270 K equal to 8.8±0.4 at. % Cr.
