摘要：
The influence of interstitial impurities on the formation of a cellular structure and on the properties of chromium is studied. They are found to hinder the formation of a misoriented cellular structure and also to raise the ductile-brittle transition point, with a simultaneous increase in microstrains DELTA a/a. The process governing the variations in DELTA a/a and T//x is found to be the segregation of impurities at cell walls. The influence of individual impurities depends on their solubility, diffusive mobility in chromium and atomic radius.
