摘　　要：概述了含铌铸铁,含硼铸铁,含钒、钛、稀土白口铸铁,镍硬铸铁和高铬白口铸铁生产工艺的进展情况;介绍了在各种不同磨料磨损条件下高铬铸铁的化学成分及显微组织的恰当选择;指出通过细化碳化物,高铬白口铸铁的冲击韧性可以得到提高。Technology progress of cast iron containing niobium,boron cast iron,white cast iron containing V,Ti,RE,Ni-hard white cast iron and High-Cr white cast iron was reviewed. Under various abrasions conditions,composition and microstrure option of high-Cr white cast iron is commented. It is possible to increase the impact toughness of the high-Cr white cast iron by refining carbide.
