摘要
研究钒对贝氏体球墨铸铁组织和性能的影响。研究结果表明 ,随着钒加入量的增加 ,贝氏体组织数量增加 ,贝氏体针尺寸明显减小 ,贝氏体球铁的宏观硬度提高 ,但钒对贝氏体球铁中奥氏体和贝氏体组织的显微硬度影响不大。测定了钒在贝氏体球铁中的存在形态 。
Effect of vanadium on structure and properties of bainite ductile cast iron has been studied in present research The results show that as the content of vanadium is increased, the content of bainite is increased, the size of bainite needles is decreased and the macro hardness of bainite ductile cast iron is increased, but vanadium has less effect on the micro hardness of austenite and bainite The morphology of vanadium carbide in bainite ductile cast iron is determined and the action mechanism of vanadium is discussed in this paper
