Manufacturing of Conductive, Wear-Resistant Nanoreinforced Cu-Ti Alloys Using Partially Oxidized Electrolytic Copper Powder.

Reactive powder composites Cu-(0-15%)TiH containing up to 5% native CuO were manufactured by high energy ball milling and then hot-pressed to produce bulk nanostructured copper-matrix alloys reinforced by CuTiO inclusions. Two high-energy ball-milling (HEBM) protocols were employed for the fabrication of Cu-Ti alloys: single-stage and two-stage ball milling, resulting in an order of magnitude refinement of TiH particles in the reactive mixtures. Single-stage HEBM processing led to the partial retention of Ti in the microstructure of hot-pressed specimens as the α-Ti phase and formation of fine-grained (100-200 nm) copper matrix interspersed with 5-20 nm CuTiO precipitates, whereas the two-stage HEBM led to the complete conversion of TiH into the CuTiO phase during the hot pressing but produced a coarser copper matrix (1-2 μm) with 0.
