| 摘 要： | 研究了钒对中铬白口铸铁的组织与性能的影响.采用SEM与EDS对试样进行了组织与成分分析,并测定了试样的冲击韧性、硬度等力学性能.结果表明:随着V含量的增加,中铬白口铸铁的组织得到细化,冲击韧性得到改善;当V的加入量增加至4%(质量分数)时,基体上弥散分布大量VC颗粒,使得材料有潜在的良好的耐磨性能.

| Abstract: | In order to study the effect of vanadium addition on the microstructure and properties of medium chromium white cast iron, the microstructure and composition of samples made of the cast iron were analyzed by SEM and EDS. The impact energy and Rockwell hardness of the samples were tested. The results indicate that with an increase in vanadium content, the microstructure of medium chromium white cast iron becomes finer and the impact energy values are enhanced. When the mass fraction of vanadium exceeds 4%, a large amount of VC precipitates occur, which make the cast iron have potentially favorable wear resistance. |
