    摘要:

    在超細WC-Co復合粉中復合添加不同含量的晶粒長大抑制劑VC和Cr3C2，利用X射線衍射儀分析粉末及硬質(zhì)合金的物相組成，通過掃描電鏡和透射電鏡觀察硬質(zhì)合金的形貌，研究不同含量的晶粒長大抑制劑對硬質(zhì)合金的顯微組織和力學性能影響規(guī)律。結(jié)果表明：隨著晶粒長大抑制劑的增加，晶粒異常長大現(xiàn)象消失，晶粒細小均勻；同時發(fā)現(xiàn)在WC-Co復合粉中VC的增加可以快速提高硬質(zhì)合金的硬度，而適量的Cr3C2可以有效提高硬質(zhì)合金的橫向斷裂強度。

    Abstract:

    With adding various contents of combined grain growth inhibitors (GGI) VC and Cr3C2 into the ultrafine WC-Co composite powder, the effects of the GGI addition on the phase constitution, microstructure and mechanical properties of the cemented carbides have been investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), respectively. The result shows that with the content of GGI increasing in the composite powder, the abnormal grain growth disappears and homogeneous ultrafine grain structure forms. The hardness of cemented carbides can be improved effectively with increasing the addition of VC, while enhancements of the transverse rupture strength (TRS) depends more on the Cr3C2 addition.
