Conclusions 1. Rare-earth metals have a substantial effect on the amount, size, and composition of nonmetallic inclusions in austenitic chromium-nickel steel, and also modify the composition and quantitative relationship between spinels and silicates. 2. Rare-earth metals increase the ductility of the steel in long-term tests. With increasing concentrations of rare-earth metals the time before fracture first increases sharply, reaching a maximum at 0.1%, and then decreases to the original value. The creep rate first decreases or does not change, and then increases sharply. 3. The scale resistance of austenitic chromium-nickel steels is increased considerably by the addition of rare-earth metals. 4. Rare-earth metals have no effect on the grain size of the steel or the resistance to intercrystalline corrosion.
