Chemical composition of grain boundaries was studied by AES on fracture surfaces of polycrystalline Ni-Sb alloy samples dominant antimony segregation was observed at the grain boundaries. By quantification of the AES results, the temperature dependence of grain boundary composition was determined and correlated with the Guttman model of interfacial solute segregation in multicomp. syst.
