Abstract

The present work studies the effect of iron on microstructure, mechanical properties and corrosion behavior of Ti-25Nb based system with emphasis on improving strength/modulus ratio. Experimental data shows that cast Ti-25Nb-3Fe has a β phase with a entirely of dendrite morphology. The bending strength/modulus ratio is 24.6 higher than Ti-6Al-4V (17.4) by 41.4% and than c.p. Ti (9.3) by 165%. The critical anodic current density of the metal in 37°C Hank's solutions is lower than approximately 100 μA/cm². Ti-25Nb-3Fe alloy has a great potential for use as an implant material.
