摘　　要：综述了稀土元素对硬质合金颗粒均匀化的作用、固溶强化作用、对晶界的净化作用、对Co相的作用及对硬质合金的强韧化作用,但这些作用机理并未得到完全认同,还需深入研究。在此基础上探讨了稀土硬质合金未来研究的方向,为稀土硬质合金的产业化提供参考。The effects are reviewed of rare earth elements on particle homogenization, solid solution strengthening,grain boundary purification, Co phase and strengthening-toughening of cemented carbides. However,the effect mechanism has not been fully recognized,needing further study. And then the future research direction of rare earth cemented carbides is discussed, to provide reference for the industrialization of rare earth cemented carbides.
