Abstract: The intergranular carbides may significantly increase rupture life and ductility of the Fe-15Cr-25Ni alloy.This seems due to the grain boundary sliding and diffusion hindered by precipitation of intergranular carbides,so the nucleation and growth rate of cracks or cavities are reduced.

Key words: intergranular carbide, creep rupture, Fe-15Cr-25Ni alloy
