Abstract

Abstract

Alloying functions of rare earth metals （REM） in iron and steels are discussed. REM have limited solid solubilities in iron, but they strongly tend to segregate to the grain boundaries. They effect phase transformation in steels and also the morphologies of the transforma tionproducts. REM have a significant influence on the mechanical properties of steels, particularly on those closely related to the properties of the grain boundaries.
