The effect of hot-press sintering temperature on density of heavy alloys WNi5Cu3

The effect of hot-press sintering temperature on density of tungsten heavy alloys is presented in this paper. The experiments were performed for the WNi5Cu3 samples of W-Ni-Cu heavy alloy system. The hot-press sintering temperature was ranged from 1300 to 1440 °c with a constant applied pressure of 40 MPa. Subsequently, the sintered samples were annealed at 1000 °c in acgon atmosphere during 3 h. The results showed that the obtained heavy alloys had maximum density of 17,427 g.cm3 and final particle size around (10 + 15) mm. The obtained results met the requirement for fabrication of small balanced parts for aeronautical industry.
