Fabrication of porous TiNb alloy incorporated with TiH2 powder by powder metallurgy processing route for implant applications / Siti Mariana Hosnie

In the development of implant material, TiNb alloy has become a great interest due to promising mechanical properties that mimic human bone. The promising mechanical properties were due to the present of the β-rich phase in the alloy. Since concern was raised toward the high manufacturing cost, the present study introduced a new approach of using TiH2 powder, which is cheaper as a reactant instead of Ti powder that is normally employed to fabricate TiNb alloy. In the present study, TiNb alloy had been successfully fabricated via powder metallurgy (PM) processing route under argon environment. The TiNb alloy was fabricated to a composition of 10, 25, 40 and 45 (weight%) of Nb.
