钒在高铬铸铁中的作用

The Effect of V in High Cr Cast Iron

在高铬铸铁15—2—1中加入元素钒,能细化铸铁的金相组织,提高机械性能,同时,加强了在腐蚀介质中的耐磨性.当含钒量大于5%时,可在铸态下使高铬铁的基体全部变为马氏体.

The alloy element V was added into high-Cr cast iron 15-2-1 and the effect of V was investigated widely. The experiment results and theoretical analysis show that the morphology of high Cr cast iron is fined by adding V into the cast iron. When the a-mount of V is more than 5%, the total matrix phase of the cast iron becomes martensite and the ca.st iron is of high hardness, toughness, resistance to wear resistance to corrosion
