Design of Ti64/Ta Hybrid Materials by Powder Metallurgy Mimicking Bone Structure.

This work reports on the fabrication of a novel two-layer material composed of a porous tantalum core and a dense Ti6Al4V (Ti64) shell by powder metallurgy. The porous core was obtained by mixing Ta particles and salt space-holders to create large pores, the green compact was obtained by pressing. The sintering behavior of the two-layer sample was studied by dilatometry.

Sintering Analysis of Porous Ti/xTa Alloys Fabricated from Elemental Powders.

The present work is focused on developing Ti-xTa porous alloys processed by the space holder method and solid-state sintering. The volume fraction of Ta ranged between 20 and 30 wt.%.
