Abstract
Chromium has limited solubility in -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.
铬在-铁中的溶解度有限。结果表明，不饱和Fe-Cr合金应表现为短程有序(即Fe和Cr原子倾向于相邻)。低温电子辐照后的残余电阻率恢复数据揭示了几种Fe-Cr合金的短程有序类型。综合考虑了570k (Scr)下短程有序度和铬溶解度的数据。Mater. 2014 v. 74，第48页，同上2016 v. 122，第31页)给出270 K附近溶解度极限的置信区间等于8.8±0.4 at。% Cr。
