fabrication of porous segments using ti-6al-4v chips for orthopaedic applications

different methods have been evaluated for manufacturing the porous ti6al4v alloys according todecreasing stress shielding phenomenon and increasing mechanical compatibility between themetallic components and the host tissue. for this purpose, in this work ti6al4v alloy chips werepressed under 400 mpa pressure and then samples were categorized and heated into two groups at1000 and 1150℃ under a vacuum about 10-4 mbar. the results implied a porosity about 35%,significant reduction of density in prepared segments comparing to bulk ones and a, reduction in theelasticity modulus and better matching with the host cancellous bone tissue. according to theresults one can expect to manufacture porous ti6al4vorthopaedic and dental implants using thediscussed method.
