Abstract

Effect of creep tensile stress on the precipitation behavior of Laves phase in Fe–10%Cr–W alloys has been investigated. Fe–10%Cr–W alloys are basic alloys of ferritic heat resisting steels, which have been being developed for the ultra-super critical pressure power generating plants. It has been clarified that the creep tensile stress enhances the Laves phase precipitation comparing with that in the same alloys aged under no stress.
