Fabrication of biomimetic titanium laminated material using flakes powder metallurgy

Inspired from the microstructure of natural biological materials, a laminated titanium material was successfully elaborated using a novel approach of "flakes powder metallurgy." Ti flakes powders, used as building blocks of the layers microstructure, were prepared by ball milling. They were then assembled into fully dense laminated materials using the spark plasma sintering technique. The results show (1) an anisotropy microstructure of the sintered material prepared from the flakes powder, (2) 15% of contribution of the lamellar architecture to the strength (hardness) of the material, and (3) faster densification of the flakes powder compared to unmilled powder.
