New study concerning development of application of rare earth metals in steels

There are three main roles of rare earth metals played in steels, which are modification of inclusions, deep purifying steel, and alloying. The effect of deep purifying steel means that deep deoxidation, desulfurization, and removing or depressing P, S, As, Sb, Bi, Pb, Sn nocuous actions in steels....

Zusammenfassung:There are three main roles of rare earth metals played in steels, which are modification of inclusions, deep purifying steel, and alloying. The effect of deep purifying steel means that deep deoxidation, desulfurization, and removing or depressing P, S, As, Sb, Bi, Pb, Sn nocuous actions in steels. The new study results concerning the development of application of rare earth metals in steels have been covered in this paper. The mechanism of corrosion resistance in the RE-weather resistance steel was clarified. The mechanism of abrasion resistance and the life of fatigue enhanced in the RE-heavy rails steel were discussed.
