Sintering of copper-tungsten materials
- 24 Downloads
To protect the Cu matrix of copper-tungsten compacts against “hydrogen sickness,” the starting compact porosity should be kept close to 20%. Resintering is accompanied by an increase in specimen volume, which grows with rise in tungsten content. The increase in volume is brought about by reduction-oxidation processes. No reaction has been observed between the metallic components of the system.
