摘　　要：利用正交实验研究了RE-V-Ti-B复合变质对15Cr-2Mo铸铁强韧性的影响,结果表明,当复合变质剂的加入量为0 3%RE-0 1%V-0 2%Ti-0 1%B时,能显著细化组织,使组织中的网状碳化物变为粒状或条状,此时强韧性最佳。The effect of RE-V-Ti-B compound modificator on the intensified toughness of 15Cr-2Mo cast iron have been investigated on the base of orthogonal tests.It is demonstrated that the modificator can make the particle smaller by turning the reticulation into part or bar like carbides and make the Cr15Mo2 cast iron obtain optimum intensified toughness value when the modificator has 0.3%RE-0.1%V-0.2%Ti-0.1%B.
