Porous titanium with good strength and three-dimension pore structure was fabricated by using TiH2 as vesicantfoaming titanium powder. This kind of porous titanium with good bio-mechanical compatibility may have the potential toalleviate the problems caused by the mismatch of the strength and Youngs modulus between implant (110 GPa for titanium)and bone. Moreover, the pores (mainly in 100-700 µm) are all interconnected. This porous structure would endow thematerials with better activity between bone and porous implant matrix. Furthermore, biocompatible porous titanium with aporosity of 33.51-49.09 vol.%, a compressive strength of 156.19-173.34 MPa and a hardness of 438.51-461.40 is known tobe a good candidate material for use as bone implants. In the present study, porous titanium was fabricated by using apowder metallurgical process. The effects of process variables, such as the size of the foaming agent and the sinteringtemperature, on the pore structure and the mechanical properties were investigated. The relationships between the porestructure and the mechanical properties were also studied.
