摘　　要：利用稀土元素的特殊作用开发高性能稀土钢,对包头稀土资源利用和钢铁技术进步有重要意义,而明晰稀土在钢中的定量行为,是开发稀土钢的关键。文章分别从钢中稀土元素热力学、稀土夹杂物形核、稀土内耗机制等方面探讨了钢中稀土元素的行为和机理,同时介绍了稀土夹杂物的无损伤表征方法。The development of high performance rare earth steel with special effects of rare earth elements is of great significances for the utilization of rare earth resources and technological progress of iron and steel in Baotou,while it is the key for developing rare earth steel to clear the quantitative behavior of rare earth in steel.In the paper,the behaviors and mechanisms of rare earth elements in steel are discussed from such aspects as their thermodynamics,nucleation of rare earth inclusions and mechanism of internal friction for rare earth.Moreover,the non destructive characterization methods of rare earth inclusions are introduced.
