Abstract
In the present study, Ti-6A1-4fe alloy was developed as a cost effective option to replace the traditional Ti-6Al4V alloy in the manufacture of surgical implants because of its larger biocompatibility (free vanadium). This alloy was prepared using the ball milling technique. Novel Ti 6Al-4fe alloy foams with porosity of approximately 70% were fabricated by a space-holder and powder metallurgical process. Irregular NaCl powders with particle size ranging from 100 to 600 um were used as a space holder material. The NaCl in the green compact was removed in hot distilled water at 70°C for times ranging from 1 to 5 h. The sintering process was performed in a vacuum furnace at 1250°C for 2 h. The T1-6A1-4Fe alloy foams displayed an interconnected porous structure resembling bone. The compressive stress and the Young's modulus of the Ti-6A1-4Fe foam were 38±514± GPa and 10.42 GPa, respectively. Both the porous structure and the mechanical properties of the Ti-6Al-4Fe foam were very close to those of natural bone.
