稀土元素在钢铁材料中的应用对优化其性能具有重要意义.文章以稀土元素铈(Ce)作为主要添加剂,制备了一种稀土TiC颗粒增强的耐磨钢,并系统地探讨了终冷温度对其组织和耐磨性能的影响.微观组织分析表明,凝固过程中铈元素能够有效地细化铸态组织中的长条链状TiC颗粒,轧制过程中,残余奥氏体含量会随着终冷温度的降低有所减少.磨损试验表明,稀土铈微合金化的TiC颗粒能够有效阻碍磨损的进行,从而提高钢板的耐磨性能.
Effects of Finish Cooling Temperature on Microstructure and Properties of Reinforced Wear Resistant Steel with Rare Earth TiC Particle
The applications of rare earth elements in steel materials play an important role in optimizing their performances. In the paper,it is introduced a type of reinforced wear resistant steel with rare earth TiC particle is prepared by taking rare earth element Ce as main additive as well as systematically discussed the effects of finish cooling temperature on its microstructure and wear resistance. The microstructure analysis indicated that the Ce element could effectively refine the TiC particle with long strip and chain shape in as-cast structure during solidification process as well as the content of retained austenite could be reduced with finish cooling temperature decreased during rolling process. The abrasion test showed that the microalloying TiC particle with rare earth element Ce could effectively prevent abrasion so that the wear re-sistance of plate could be improved.
