摘要	Effects of chemical composition on grain boundary microchemistry and stress corrosion cracking (SCC) in two kinds of modified Alloy 182 with different hot-cracking resistance were investigated. The results showed that while decreasing concentrations of C, P and S but increasing the concentration ratio of (Nb + Ta)/Si can enhance hot-cracking resistance of the alloy, SCC susceptibility in primary water was promoted simultaneously, which is most likely due to the lowered creep resistance by a lower precipitate density and less P segregation at the grain boundary in the alloy.
