Formation of structure and properties in extruded silver and silver-nickel materials

Conclusions

• 1. Extrusion generates texture in sintered silver specimens already at a reduction of 64%.

• 2. The addition of nickel to a silver matrix inhibits texture formation. The appearance of texture is influenced by the amount and size of nickel grains.

• 3. The theoretical density and electrical conductivity of silver and silver-nickel specimens are attained at a reduction of 64%.

• 4. The deformation of silver and silver-nickel pseudo alloy specimens begins at the specimen surface and spreads inward. In a pseudo alloy, the matrix deforms first; the nickel grains begin to deform after the hardness of the matrix attains, as a result of deformation, their hardness.
