Activated sintering of tungsten with small additions of nickel
- 46 Downloads
During the sintering of tungsten with 0.5% nickel, shrinkage of specimens was observed at temperatures as low as 1100°C. It is shown that the sintering process is not affected by the method of introduction of nickel. A W-Ni solid solution appeared during sintering along the grain boundaries. The formation of a second phase was confirmed by electron microprobe analysis.
