Effect of Doping Elements on Microstructure and Grain Growth of Cemented Carbides

Keywords： cemented carbide , doping , inhibitors , grain

介绍了钴、镍、硅等结合剂在硬质合金生产中的应用及对其烧结工艺的影响,系统论述了钒、铬、妮、钽、钼、铱等10余种元素及其化合物的掺杂种类、掺杂方式、掺杂数量对硬质合金微观结构和性能的影响,在综合大量文献的基础上,阐述了各种晶粒生长抑制剂对WC晶粒生长、晶粒尺寸的抑制效果差异及作用机理的不同,以及各种晶粒生长抑制剂合理的掺杂量.这些研究内容将对硬质合金生产,特别是制备新型硬质合金材料有着重要的参考价值.
