Abstract: Tungsten heavy alloys are widely used in ballistic applications due to their superior mechanical properties. This study is focused on the microstructural and mechanical characterization of liquid phase sintered 93W-5.6Ni-1.4Fe alloy. The powder mixture was cold isostatically pressed at 300 MPa and sintered at 1500 °C under hydrogen and argon mixture for 30 minutes. Compression tests were performed with the cross head speeds of 5x10-1 - 5x10-3 mm/s. Samples were characterized by scanning electron microscopy study and microhardness measurements. The results showed that the increase in crosshead speed at compression tests caused slight increases at yield strengths and microhardness of the alloy. © European Powder Metallurgy Association (EPMA).
