摘要
对几种国产和进口的ＷＣ—Ｃｏ类硬质合金制造的拉深模具进行了断裂失效分析，结果表明，其失效的起因与材质及ＷＣ颗粒度和颗粒均匀性有密切联系。在其失效分析的基础上。
The fracture failure of some drawing dies made of WC-Co hard alloys made at home or abroad are analyzed in this paper.The results show that the failure causes are close correlative with the WC granularity and granular uniform.Finally,some material selection principles for these draning dies are suggested.
