Intragranular polarization of electronic сharge in metals and her influence on the grain-boundary segregation of admixture elements

From the standpoint of electronic theory the features of the formation of grain-border segregation of alloying elements in binary alloys based on iron in the high-temperature region T>0.6 Tm were considered. The values of the binding energy of the atoms of the elements: Mn, Ni, Si, V, Al, Ti and Nb with the grain boundary were calculated and the level of their grain-border segregation СГ/С0 in binary Fe-Me solutions at 1100 K was estimated
