Abstract
Nanopowders of TiCo were synthesized from Ti and Co by high energy ball milling. Highly dense nanostructured TiCo compounds were consolidated at low temperature by pulsed current activated sintering within 3 minutes from the mechanical synthesis of the powders (TiCo) and horizontal milled Ti+Co powders under 100 Mpa pressure. This process allows very quick densification to near theoretical density and prohibits grain growth in nanostructured materials. The grain sizes of the TiCo compounds were calculated. Finally, the average hardness values of the nanostructured TiCo compounds were investigated.
Key Words
TiCo, nanostructure, sintering, mechanical properties
