Abstract
Extensive creep cavitation precluded the beneficial effect of Cu addition on long-term creep rupture strength of 18Cr–12Ni–Nb (type 347) austenitic stainless steel. Microalloying with B and Ce suppressed creep cavitation to increase its creep rupture strength and ductility. Boron segregation on nucleated cavity surface instead of S retarded its growth. Cerium acted as a getter for soluble S to prevent its segregation on cavity surface.
