    Like rare earth elements such as Ca, Ti, Zr, Mg, and Be, it is the most effective deforming agent for sulfides. Adding an appropriate amount of RE to the steel can cause the oxide and sulfide inclusions to become finely dispersed spherical inclusions, thereby eliminating the hazard of inclusions such as :// 33 Data References要点_幼儿读物_幼儿教育_教育专区 10人阅读|次下载 33 Data References要点_幼儿读物_幼儿教育_教育专区。33 Data References

For example, Y, Sc, and Ti sulfides have ΔH (per mole of solid S) that are much more negative than MoS2, meaning the sulfur atoms in MoS2 prefer to bond with Y, Sc, and Ti than Mo, assuming small entropies of formation and no kinetic limitations.

It has been proven that adding lanthanum has a significant effect Gigantic magnetism expected for α″-Fe16N2 thin films had been attracted much attention in terms of its large magnetization per weight in comparison to rare earth iron nitrides R2Fe17N3 because Like carbides, nitride inclusion contents in steel are significantly less than that of oxides and sulphides.
