Abstract: | The equilibrium segregation A (dissolved) = A (segregated), where A = C, Si, Sn, N, P, O, S … is studied for binary systems Fe-A in the stability range of the α-solid solution using surface-analytical methods. On the surfaces ordered structures were observed by LEED and surface concentrations were determined by AES – in dependence on bulk concentrations and temperature. The chemical binding state was characterized by XPS. In grain boundaries the segregation was determined by AES after intergranular fracture of samples. A survey is given of the existing results. |
