摘　　要：A new tungsten heavy alloy, W-Ni-Fe-TiB_2 was studied. This ally has higher hardness than tradition-al tungsten heavy alloy. Sintering time was 30 min for producing the alloy. In the new tungsten heavy alloy, four phases were found to be W, γ (Ni, Fe), TiB_2 and complex haride compound. TiB_2 and complexboride compound were precipitated in the matrix. So TiB_2 could strengthen the tungsten heavy alloy.A new tungsten heavy alloy, W-Ni-Fe-TiB_2 was studied. This ally has higher hardness than tradition-al tungsten heavy alloy.
