摘　　要：研究了VCp/Fe复合材料在紧固件冷镦模中的应用。结果表明,由于VC增强颗粒的强化作用,VCp/Fe复合材料在铸态就具有较好的力学性能。通过适当的强韧化处理,综合力学性能大幅度提高。与Cr12Mo V材质的锻造冷镦模具相比,VCp/Fe复合材料冷镦模的使用寿命延长了50%~60%,而且简化了制造工序,缩短了制造周期,降低了制造成本。The application of VCpFe composite in cold heading die for fasteners was investigated. The results show that VCp/Fe composite presents outstanding mechanical properties in the cast state due to the strengthening effect of the VC particles. The comprehensive mechanical properties are greatly improved after the appropriate toughening treatment. Compared with forging cold heading die Cr12MoV, the service life of VCp/Fe composite cold heading die will prolong 50%--60%, and the manufacturing process is simplified, the cycle will shorten and the cost will reduce. Therefore, the VCp/Fe composite is promising in application.
