| 摘 要： | 利用微波烧结技术，研究了添加VC／CBQ晶粒生长抑制剂对WC-10Co超细硬质合金微观结构及性能的影响。结果表明，添加总量质量分数为0．6％的抑制剂的合金的综合性能最好，过量的抑制剂反而会降低合金性能；并且微波烧结合金不论是否有晶粒长大抑制剂，均能得到均匀的细晶结构。

| Abstract: | Using the microwave sintering technology, the effects of VC/Cr3C2 additions on the microstructure and properties of the ultrafine WC-10Co alloys were investigated, Experimental results showed that ultrafine WC-10Co alloys with 0.6 % additions had the best properties while the excessive grain growth inhibitors would decrease the properties of alloys. Moreover, with or without additions, WC-10Co alloys with finely uniform grained WC by microwave sintering could be obtained. |
