The effects of Y,Ce and La on the sulfidation of alloy Fe-25Cr-40Ni have been investigated. The sulfidation rate of the alloys with RE more than 0.1 wt-% is lower than that of the base alloy.The addition of Y is more effective than La and Ce in lowering the sulfidation rate. Based on the analyses of...
