摘　　要：对Cr12MoV模具钢进行Ti变质处理,以改善铸态下钢中共晶碳化物形态及分布,并对变质处理后钢的力学性能进行了分析。结果表明,Cr12MoV钢经Ti变质处理后,钢中共晶碳化物的分布得到了改善,同时,钢的硬度有所降低,抗拉强度得到提高,冲击韧度提高了2.8倍。In order to improve the morphology and distribution of eutectie carbides in as-cast Crl2MoV mold steel, the modification treatment of the steel with Ti was carried out. The results show that, after modification treatment with Ti, the distribution of carbides in Crl2MoV steel improves. And the hardness of the steel decreases, the tensile strength increases, especially, the impact toughness is increased by about 2.8 times.
