摘要
在球墨铸铁中添加镍和铬元素,研究其对组织与性能的影响。结果表明,向QT450-10-10牌号球铁中适量复合添加镍、铬可以生产高性能的球墨铸铁,显著细化晶粒,提高硬度、拉伸强度及耐蚀性能。镍对冲击性能的提高更加明显。
The effects of nickel and chromium on the microstrueture and mechanical properties of ductile iron were studied. The results show that the nickel and chromium can be used to produce high performance QT450-10-10 spheroidal graphite cast iron, which can improve the hardness, tensile strength and corrosion resistance. The effect of nickel on impact performance is more obvious.
