Abstract
⺠Grain boundary segregation in Alloy 690 was investigated by atom probe tomography. ⺠B, C and Si segregate at the grain boundary. ⺠Concentration of segregated atoms periodicity fluctuated in the grain boundary plane. ⺠C and Cr co-segregate on one side of the grain boundary before carbide nucleation.
