ABSTRACT
Bone implantation is common since several decades. Titanium alloys are the most commonly used bone implant
materials. TI-27Nb (Titanium-27% Niobium) having no toxic effects on human body and also having low modulus.
The objective of this paper is the mechanical characterization of TI-27Nb. Tensile, hardness, microscopy and scanning
electron microscope tests were conducted on TI-27Nb specimens. The tensile strength and young modulus of TI-27Nb
were lower than commonly used Titanium alloy i.e Ti-6Al-4V. The SEM results show mixed brittle-ductile surfaces.
It is concluded that TI-27Nb has lower stress shielding/bone restoration because of low modulus than commonly
used implant materials.
