研究了2种不同类型（W，Ti）（C，N）固溶体及氮含量对硬质合金组织和性能的影响，结果表明：含氮硬质含金不仅可从细化（W，Ti）（C，N）晶粒，而且还可细化WC晶粒。
The effects of two different types of (W, Ti) (C, N) solid solution and nitrogen content on the microstructure and properties of the cemented carbide were studied. The results show that the nitrogen-containing hard gold content can be obtained not only from the refinement of C, N) grains, but also WC grains can be refined.
