摘　　要：研究了稀土硅铁合金在4Cr5MoSiV钢中的作用,在钢包中加入0.03%稀土硅铁合金,观察试样的显微组织、磨损形貌并测试其力学性能。结果表明,稀土硅铁合金的加入能起到细化晶粒的作用,显著提高4Cr5MoSiV钢的强度、冲击韧度和耐磨性。：The role of RE Si-Fe alloy in 4CrSMoSiV steel was studied, and 0.03% RE was added into the steel liqiud. The microstructure and worn-out appearance was observed and the mechanical properties were measured. The results show that RE addition can refme grain, and significantly increase the strength, wear resistance and impact toughness of 4Cr5MoSiV steel.
