Abstract:

The objective of this research was to explore a novel alloy development via powder processing combined with innovative consolidation methodologies to fabricate laboratory-scale parts made from nanocrystalline Cu-Ta based alloys with thermal stability, ultra high-strength and hardness, and wear properties suitable for substitution for Cu-Be applications. Specifically, high-energy ball milling was used to fabricate non-toxic nanostructured Cu-Ta based alloy powders with a unique ability to retain their ultra high-strength properties to temperatures nearing the melting point of the Cu alloy.
