The Behavior of Rare Earths in Steel

Abstract

Abstract: This review paper outlines recent progress in the application of rare earth metals (RE) in steel to improve the mechanical properties of steel. It includes: the physical chemistry of RE in steel; comparison of the application of RE and Ca in steel; the ways of adding RE into steel and nozzle blockage; the solid solubi- lity limit of RE in Fe and the amount of RE soluble in steel; the segregation of RE on grain boundaries of steel and its reaction with other elements; the effect of RE on the structure and mechanical properties of steels; the reaction of RE with H in steel.

Key words: rare earths, segyegation, mechanical properties, hydrogen induced cracking
